This video right here is exactly why i am a patreon supporter of BBI. I mean when the heck ever is an old mud duck radio guy like me who probably will never break the 300 watt barrier in my entire life....where would i ever get to play with a friggin 10 kilowatt transmitter? Its as if the mad proffesor lets me into his labratory and the entire time he is explaning every small detail about whats going on with the latest experiment. Its really a the funnest time of a day when the newest BBI video comes out. Thanks a bunch BBI for all the teaching you do for us all. You will always have me on your patreon list. The DragN'Fly in Tennessee said that.
Thanks bbi. I'm going to fire up my rci 2995 and my sb 220 and think I have something. Just watching the video makes me want to key up and slang some rf in the air. Ironman in Alabama 73s
Always top notch video teaching and learning the best things to do with your equipment. Very educational to people who want to learn in the people just getting into it thanks again for everything you do for the hobby.
BBI...I have been trolling your channel again for a few weeks now. Used to watch back several years ago, glad to be back. What an amazing deal some lucky person got there. That to me is the gold standard of amp...love the old glass stuff. Not that you need to hear this, but that was a very honorable amount of work you did to help out the family with that project. Seems like just the kind of dude you are. Look forward to getting to work with you myself someday. Headed off to the Patreon now bud...73's
Hello .. I was a CB/11 meter fanatic back in the 70's, 80's and very early 90's. Had so much fun. Would get on AM in the evenings and SSB in the afternoons. Had a 2 element quad on top of an 88 foot (tilt over) pipe tower. A 5/8 wave vertical for a backup. It was amazing. I run a President Madison into a Boomerang Amp. The tube amp just plugged into the mains. I had few smaller amps, but the boomer was by far the best. If I remember correctly it had a lighted rocker on/off switch and 5 toggle switches on the front, a large meter and a tune and load control. You couldn't miss the name .. Boomerang in big redish-orange letters. It had a pre-amp / boost receive that worked really well. It was one of the 5 toggle switches. I can't remember exactly what they all did now. Think - ssb/am | boost receive | hi/lo | by pass / stand by maybe? Been close to 40 years ago now. I sold the thing around 2004 and the guy burned her up .. running into a broken antenna. Sad .. I need a new amp. Anyone else have a boomerang?
Your big Amp looks a lot like an older RF laser driver I got to play with. Pumped 6kW of 27MHz RF through the co2 lasing tube, with a 2KW beam output about the diameter of a quarter.
Excellent straight board presentation on this amplifier.. Well demonstrated by you of course BBI.. It would be a dream down that.. and the price you put on it is just extremely fair and unbelievable., for this grade of equipment.. I enjoy your videos, I'm into electronics have been for many years. Myself I have a pride DX300 that was left to me by a friend that passed. It has problems on the capacitor boards. And I intend to purchase new boards and get it online it's got to steel tube in it.. can't wait to get it up and running and memory of my beloved friend fast Eddie... Thank you for the great presentation.. keep rocking and stay cool. And by all means keep up the great work.. Sincerely; C Kirkland... Kansas City Missouri....
I wish tubes didn’t scare me so much. I love how effortlessly it makes power with low drive. Just cruising. Probably never gonna have another base station either.
that a super amp. looks like all grids ground. that another way to run them. only thing i would add is some safety interlock switches ground HV remove 240V in. and a voltmeter for the filament. it would be ok to back down filament voltage before turning off filament supply. how we do big broadcast tubes. a cabinet ground is a must on any amp like that. 73's
Man I love the old school shit where it shows thought into the item, craftsmanship,it is just hard to find backup parts. I miss tinkering .my stroke took my tinkering fixing odd and ends away from me. That amp is standard to operate. That was a pretty and sexy peace equipment. Love it❤. But my radio days are mostly over after my stroke.
bad design, filament leads coping up on top RF deck, biggest no-no in building 101. always below deck with chokes and caps if a fault occurs. otherwise RF will leak back through it all, probably even go into oscillations and nuke itself on the wrong band or harmonics. poof.
Love the glow in the dark equipment, I am surprised that it doesn’t have a dead man switch like old broadcast transmitters . Enjoyed your video and all the details.👍. KC5HHB Delmar
Your asking price is more than fair! You did a really good job presenting this amp. As to RUclips, RUclips treats all of their content up-loaders like garbage... Welcome to RUclips...
Man... 3,500 is a freaking STEAL for this sweet talking machine. If I still played on the band, I'd snatch this up in a heartbeat. Whoever fires down with this is gonna get their name called...no question!
I like this video as well. We radio amateurs are a the minority in today society. I like to fiddle with old radio/amp stuff. I do not own such beautiful old RF amp, but a homebrew audio amp , 2x 1500W with 4 of the GU81 valves. (2 monoaural) amps It run with 2700V at the plates. I had a lot of fun while build it. My transmitter is an relativ modern Transistor version made by german company named HAGENUK. It drive impressive 1500W into the antenna. Not that spectaculary beast like an valve amp of the same output.:(
Mr. BBI, I operate a small technology company refurbishing used Electron microscopes and X-ray microscopes up to 225KV DC. I agree with you that doing anything to try to improve a tube's vacuum is a waste of time. The only way to do that would be to put it back on a UHV pumping system then, resealing it. A Getter is the internal silvery coating of pure titanium that is seen inside many tubes. Titanium is used because it has a high affinity for Oxygen and other halogen (highly ionically reactive) gases that may have been left inside, even after high temperature baking while being pumped for days using an ionization Ultra High Vacuum pump. If a tube becomes gassy it's because it has a vacuum leak, probably as a result of rough handling that caused a micro crack at one of its' electrical feedthroughs. There's nothing that can be done to improve that. Only if you vent the tube, disassemble it to remove dielectric oxide coatings on all the electrodes, replace the base to replace the leaking feedthroughs, then repump it for several days while using an induction furnace to rebake it. You'd have installed a new coil with Ti powder that you would flash in an RF coil to create a new getter coating. It's cheaper to just replace the tube at only $550 each today. Vacuum, electron transmitting tubes are technological wonders. Are there any Metal-Ceramic tubes that'll make 10KW PEP selling at just $1100 new? I don't think so. How about LDMOS? No. Still about the lowest cost way to go is what you have right there.
Sorry BBI not my intention to offend in any way testing into a dummy load always shows zero reflect and flat SWR what I should have said is Does SWR go up when testing into antennas? because Im getting to high SWR with amp inline, barefoot its low seems like the amp and meter inline is driving up my SWR who knows what it would be if I put a small driver inline? what am I doing wrong? Your a great teacher BBI.
Excellent price!! Would have loved to have picked this up.... Maybe I should bring you my single 4-1000 box, and see if you can bring it back to life. 🤔
I dont know how I missed this when it came out. Must have been out on the trail. I'm a tube guy. Yeah they make some really good solid state legal limit plus amps but in my head they will never be as robust or sound as good as my tube amps. One ceramic tubes and one is glass. Not much difference in operation for me but the glass tubes just seem to have more personality.
filament leads that come up around on-top of an RF deck? NO! BAD! unless it's fully RF and HV isolated compartment. the only thing at RF deck level should be things that are handling the RF directly. that should really have an RF screened enclosure behind the door. yeah, I get it cost over safety, safety third etc. we've all done it on home brew and half-butt projects.
I just acquired 1/2 of that box from a silent key. It's been in a basement for over 12 years so I'm going super slow mo and checking everything. It appears to have a half wave rectifier. Why?? Can I build a full wave and stick it in??
BBI, would love to see ya build a box with a Eimac 8974/X-2159 tetrode... - Thoughts? - All Ribbing asside, mega appreciate your content, as a former broadcast engineer working on TH347 and 4cx10000D based transmitters, its fun seeing what can be done when you think/work outside the box.
Pretty sure those diodes are X-ray machine/MRI surplus of some kind. I bought a few of them a long long time ago and that's what the Ebay guy said. In an era of LDMOS amps this amp is proof that there's still cool tube amps out there. At $3500 it's a bargain, but I think you'd have a guy that comes to you asking for it not the other way around. On a setup like that, one thing I would like to have is a cabinet safety interlock. That is a heck of a lot of voltage to play around with. You likely wouldn't get a second shot if that thing gave you a hit.
WoW..Thats A Deal..IMHO..i have ben into radios sense i was 8-9yo /35+ - Years & i gota say that is sweet.. i had 2 grand ish into a old 4 tube 3-500z peace that looked like well you know..lol. i had a L4B Drake that i rebuilt & just drove it with my Pride dx 300 also All the Upgrades & Mods stock tube though that i tickled it with mostly ! Man o man the fun i could have had with this haha..
man thats a nice box..id love to get rid of the 3 z box for this. Them needle chasers hahah 😂😂😂 can we get ol smokestack to build another haha .. It is a bad box.. 4 pill or less and be done.
U best used whats paid off that's what I have 2 3.500 z in ssb 220 had it sense 2011 still has same tubes just updated wiring and caps there pretty bullet proof
The guitar amp repairman in me says no to guitar amp. We care more about what the preamplification does to the sound. Output transformer saturation is only one aspect of guitar amp sound and pretty much starts to go away at higher wattage with the bigger transformers. The output transformer for a pair of those bad boys would be way too big and heavy. Guitar amps stop being useful around 150/200 watts RMS. Most useful when they're around 25 to 50 watts. Now for a bass amp, that's a whole other story. The more, the merrier when it comes to watts. I've seen old amps using tubes like that which the hifi dorks have reused.
Oh man, the guitar amp idea... dude, dude.... This has been my basic question all along, only I didn't realize it till just now. Then 2 minutes ago I was yanked out of my stupor by your comments on the subject. This must be done. What would it take? I don't think I have a clue. But I know you do. I can't bias a transistor, or build a proper amp... But I can play the piss out of a guitar. And I can dream. Peace.
@@BoxBuilderIdahoIt was meant as a joke, your going to need some gas money for a cross country trip...how much would a cross half the planet trip set you back...
You know I have this henry 2kd classic sitting here with your name on it luke,, lol .. I want to trade it for some sweep tube equipment, I need a tube tester and a variac...
BBI I know you are gonna think i'm trolling you but the only watt meter that you have thats accurate is the middle rms meter. And it only showed a tick over 2kw on voice peaks. So no one cares about PEP take it from someone thats been building amps for 30 years if i was selling you that amp and you asked me what the power output is. Id have to say its 10:1 100 watts in 1000 watts rms out 200 watts rms in 2000 watts rms out. that way when you got home and put it on your Doesy test center and saw 4kw you would be happy
Actually most of what you just said isn't factual at all.. there is a reason that bird has developed and designed and has sold a pep kit. For a.m. operation. Matter of fact the only time the centimeter is even accurate is when the meter is being used in a side band, cw,fm measurement. The bird 43 was never designed to measure am. It's right there in the bird hand guide if you don't believe me. Now I'm taking it even though another place. I did a hold of RUclips video called why I had to put labels on my watt meters. In that video I made it very clear and I've said this over and over and over again I don't frankly care what the Meters show. I show it an all modes of operation so whoever Tunes in you can take away from it whatever they need to have to understand what the meters are displaying. There's a reason that I have a meter in pep there's another reason that I have it showing RMS or average or bird how ever you want to go by labeling it I don't really care. If all you care about is the RMS reading which isn't even real term to be used with a board 43 wattmeter the information has been presented to you. Especially now that we live in a world where we can turn the average number up and down by justing the a.m. and ejected modulation in the radio. The "bird" Watts is a variable adjustment so therefore the only thing that we have is a solid constant which also proven on video over and over and over again is the peek to peek power. Hey but what do I know I'm just following the bird instruction manual that comes with their pep kit.... Meh. That's probably why my 3 watt meters are the most copied form of measurement in the amp building industry today. Just saying. Represent all the data and all the different formats and I'm refusing to acknowledge that anybody is right or wrong. It's just my job to show the amplifier working with whatever wattmeter and whatever configuration you want so you can feel happy. Brother I appreciate the view I appreciate the comment and have a great night we well and have fun building.
No actually I'm an electrical engineer and what I said was factual my call is AJ4MT Also a Navy vet and was and aviation electronic tech while there earning my degree. I'm sorry if the truth bout RMS power upsets you. I have no desire to debate a known truth with you. I know I am right and have 30 years under my belt to prove it. All I was saying is there is no way with that plate voltage and current. 1.8 x plate voltage can you have the power pep you were showing
It's not that you're upsetting me and anyway don't get it wrong. I'm just going off with the electrical engineers at bird wrote down in their manual to describe their meter and how to go about using it with a measurement in their own book and I'm sorry if you don't want to hear me say that out loud but it's the truth. Like I said there's a reason that I presented all the information and all the different ways it can be presented. You're not going to upset me in any way ever I guarantee it. 😉 if you choose to disagree with the guys of bird... so be it. Makes no difference to me. I appreciate your input and I appreciate your comment.
BBI, you're a class act! Appreciate you stepping up for the family to help and protect them...
He neeeeds to grow up socially. Its like that guy who pretends to be AvE but isnt fucking funny and all he has to do is relax and be clever.
YES BBI is a GREAT teacher and he's pretty damn cool also.
Outstanding Luke ! You still doing mosfet amps ?
Outstanding in every way. $3500 is dirt cheap.
Thank you!
Another great one BBI. I learn something new from every one of your videos. Thanks for educating us and supporting this fun hobby!

That's an awesome unit it is bad to the bone brother I enjoy your videos
Great piece at a great price!!! Gonna make someone very happy.
Those are awesome tubes! I have several 4-1000 amps, one is a 2 x 4-1000. When ran right they will last a very long time! Nice amp
That is a beautiful box very nice build rip brother Larry

Great amazing video what a amp. thanks for your time and showing 73s Mike The Dalles OR
Love the video yeah it's feeding us some great audio no wonder smoke stack got out so well 😁
that a super amp. looks like all grids ground. that another way to run them. only thing i would add is some safety interlock switches ground HV remove 240V in. and a voltmeter for the filament. it would be ok to back down filament voltage before turning off filament supply. how we do big broadcast tubes. a cabinet ground is a must on any amp like that. 73's
Man I love the old school shit where it shows thought into the item, craftsmanship,it is just hard to find backup parts. I miss tinkering .my stroke took my tinkering fixing odd and ends away from me. That amp is standard to operate. That was a pretty and sexy peace equipment. Love it❤. But my radio days are mostly over after my stroke.
Wish that sucker had bandswitching for ham bands... I would buy it for sure.... Nice channel, love ur stuff. 73's W4PBS
Yep if only it had band switching. I would also be very interested in this. And only a 60 mile drive to deliver.
bad design, filament leads coping up on top RF deck, biggest no-no in building 101. always below deck with chokes and caps if a fault occurs. otherwise RF will leak back through it all, probably even go into oscillations and nuke itself on the wrong band or harmonics. poof.

That’s a badass box. Was so wanting to see it hooked to an antenna
You got me with the Antron and the mini 8 x. :(
awesome knowledge Mr BBI! thx for entertaining and teaching. 73

I will stick with my 2x8...that way it's much harder to kill myself lol
That will make you warm and cozy in your winter radio shack break you out in sweat and kill A/C capacity in the summer.

No no no this Sucker is electrical but I need the Nuclear fusion to make the 1.21 Jiggawatts of power ! 😂😂
DAM,THATS A HELL OF A DEAL.IF I WAS A YOUNG MAN,ID BUY IT TODAY.
I really need to hit the lottery..
BBI got to say it again I love the chicken stick, going to build one myself. Question do you have a resistor on yours? If so what is the rating?
Sorry BBI not my intention to offend in any way testing into a dummy load always shows zero reflect and flat SWR what I should have said is Does SWR go up when testing into antennas?
because Im getting to high SWR with amp inline, barefoot its low seems like the amp and meter inline is driving up my SWR who knows what it would be if I put a small driver inline? what am I doing wrong? Your a great teacher BBI.
Saludos BBI desde PR el Trebol tremendo amplificador
Excellent price!! Would have loved to have picked this up.... Maybe I should bring you my single 4-1000 box, and see if you can bring it back to life. 🤔
Just needs a Jacobs ladder for the mad scientist keys up :)

BBI Most RUclips Viewers Use a Popup/ad blocker In 5 yrs + never seen 1 ad. on any web site. Great video as always.
You know RF not as bad as i would expect. Surprised it didnt wipe out the camera.
filament leads that come up around on-top of an RF deck? NO! BAD! unless it's fully RF and HV isolated compartment.
the only thing at RF deck level should be things that are handling the RF directly. that should really have an RF screened enclosure behind the door. yeah, I get it cost over safety, safety third etc.
we've all done it on home brew and half-butt projects.
One of your best videos, love it.
12dB gain is good for a grounded grid AMP.
And 5KW out is more than enough

There used to be a "Smokestack" around Bryan Texas that built some big boxes, base and mobile.
There was a guy who ran big radios in the Palm Desert area in the early 90s that went by 'Smokestack'. I was thinking it was him.
I love how you can HEAR it work... holy shoot
Pretty sure those diodes are X-ray machine/MRI surplus of some kind. I bought a few of them a long long time ago and that's what the Ebay guy said.

It still Cheaper then a New HVAC setup..
BBi. These videos give you good advertisement for your business. That is money in itself. $$$$$
Run my 4-1000's at 6KW all day for over 10yrs and still honkin' !! Best in Glass 4-1000A
WoW..Thats A Deal..IMHO..i have ben into radios sense i was 8-9yo /35+ - Years & i gota say that is sweet.. i had 2 grand ish into a old 4 tube 3-500z peace that looked like well you know..lol. i had a L4B Drake that i rebuilt & just drove it with my Pride dx 300 also All the Upgrades & Mods stock tube though that i tickled it with mostly ! Man o man the fun i could have had with this haha..
I am not judging but am curious about one thing. First I admire your technical ability. What keeps the FCC from busting you? Serious question.
Aye are those klein screwdrivers? Is that your dads shack or something?
That was disappointing was waiting for you to plug the satellite dish sized speakers
in and rock out with the Les Paul.
That would be truly ghey.
really good price
man thats a nice box..id love to get rid of the 3 z box for this. Them needle chasers hahah 😂😂😂 can we get ol smokestack to build another haha .. It is a bad box.. 4 pill or less and be done.
U best used whats paid off that's what I have 2 3.500 z in ssb 220 had it sense 2011 still has same tubes just updated wiring and caps there pretty bullet proof
What a beast 😵💫
you can always touch those capacitors with your tongue to get a better idea how much juice is still inside
😂🤣😁
How many watts should i drive a 2pill kicker with ? I'm new to this.
Whats your grid current at 7000? You never said.
BBi. Are tubes cleaner than transistors for transmitting ?
Yes
Right on bbi great deal for someone. And I love that you won't sell it to someone cause they might die. Hell i wouldn't want that on my concience
What is your estimate on 4x4-1000a’s in an amp?? Just a ballpark figure?
Outstanding bbi.

I can't bias a transistor, or build a proper amp... But I can play the piss out of a guitar. And I can dream.
Peace.
Yup. Primate, indeed.
@@johnsmith7676 thanks.
Rock on.
By the sizes of these cabinets and that blower this must be a commercial rig
Just out of curiosity, have you figured out the Flux capacitor???
Whats the asking price
Is this a pizza oven, or a radio?
😂 let's get you a radiation suit. Yaasa
O man I like this....
i live in Germany.
Otherwise I would have bought it from you.
Thanks for the nice work!

Bet the audio is killer coming out of that big glass.
Those tubes only reproduce what’s put in. 90% modulation in you get the same out.
@@vsmichael1 Audio harmonics are slightly different, Clean Audio even when overdriven try that overdriving metal ceramics.
What was your high voltage on high?
How much to post it too Australia???
@@bitemykrank1970 its sold bud
@@BoxBuilderIdahoIt was meant as a joke, your going to need some gas money for a cross country trip...how much would a cross half the planet trip set you back...
Fook....that's a great deal.
IF you can get it to scotland.. i`ll buy it
3500 are you really giving it away???? I can't believe that cheap price.
Looking to buy a two tube 4-1000 for 40M
Wow. Wow.
Speaking of which I just dropped it off to its new owner today...
Unbelievable amp, I've said "Oh my God" so many times during the video. I want one.
Will it work on 27 MHz?
I want one 😎
thats a great deal 3500
You know I have this henry 2kd classic sitting here with your name on it luke,, lol .. I want to trade it for some sweep tube equipment, I need a tube tester and a variac...
B&k 747 tube tester its the best
I'd shit my pants if I get over 1k good lord
Guauuu para todo el mundo😮😮 My qrz torre alfa Tijuana baja California 73
BBI I know you are gonna think i'm trolling you but the only watt meter that you have thats accurate is the middle rms meter. And it only showed a tick over 2kw on voice peaks. So no one cares about PEP take it from someone thats been building amps for 30 years if i was selling you that amp and you asked me what the power output is. Id have to say its 10:1 100 watts in 1000 watts rms out 200 watts rms in 2000 watts rms out. that way when you got home and put it on your Doesy test center and saw 4kw you would be happy
Actually most of what you just said isn't factual at all.. there is a reason that bird has developed and designed and has sold a pep kit. For a.m. operation. Matter of fact the only time the centimeter is even accurate is when the meter is being used in a side band, cw,fm measurement. The bird 43 was never designed to measure am. It's right there in the bird hand guide if you don't believe me. Now I'm taking it even though another place. I did a hold of RUclips video called why I had to put labels on my watt meters. In that video I made it very clear and I've said this over and over and over again I don't frankly care what the Meters show. I show it an all modes of operation so whoever Tunes in you can take away from it whatever they need to have to understand what the meters are displaying. There's a reason that I have a meter in pep there's another reason that I have it showing RMS or average or bird how ever you want to go by labeling it I don't really care. If all you care about is the RMS reading which isn't even real term to be used with a board 43 wattmeter the information has been presented to you. Especially now that we live in a world where we can turn the average number up and down by justing the a.m. and ejected modulation in the radio. The "bird" Watts is a variable adjustment so therefore the only thing that we have is a solid constant which also proven on video over and over and over again is the peek to peek power. Hey but what do I know I'm just following the bird instruction manual that comes with their pep kit.... Meh. That's probably why my 3 watt meters are the most copied form of measurement in the amp building industry today. Just saying. Represent all the data and all the different formats and I'm refusing to acknowledge that anybody is right or wrong. It's just my job to show the amplifier working with whatever wattmeter and whatever configuration you want so you can feel happy. Brother I appreciate the view I appreciate the comment and have a great night we well and have fun building.
No actually I'm an electrical engineer and what I said was factual my call is AJ4MT Also a Navy vet and was and aviation electronic tech while there earning my degree. I'm sorry if the truth bout RMS power upsets you. I have no desire to debate a known truth with you. I know I am right and have 30 years under my belt to prove it. All I was saying is there is no way with that plate voltage and current. 1.8 x plate voltage can you have the power pep you were showing
What I saw on your rms meter is about right 6000 volts x 800 ma x%50 efficiency is about 2400 watts dead key which is what it showed haa e a nice day
It's not that you're upsetting me and anyway don't get it wrong. I'm just going off with the electrical engineers at bird wrote down in their manual to describe their meter and how to go about using it with a measurement in their own book and I'm sorry if you don't want to hear me say that out loud but it's the truth. Like I said there's a reason that I presented all the information and all the different ways it can be presented. You're not going to upset me in any way ever I guarantee it. 😉 if you choose to disagree with the guys of bird... so be it. Makes no difference to me. I appreciate your input and I appreciate your comment.
