i just finished building this amp 2 weeks ago and let me tell ya this head will blow your mind. And oh my god is it LOUD. I run mine without the rectifer tube and leave the 50 watt switch on the 50 Watt position. My signal chain is an MXR Carbon copy into an MXR gt-od, into a Boss turbo distortion, MXR 6 band eq, and then into a homemade volume attenuator to switch between rhythm volume and lead volume. Jumper the inputs, and tinker until you get the tone you want. You will not be disapointed!
That's what I used to do all day long! I did start off slow, but by the time I finished working there I was up to 2 full amp chassis per day. And I LOVED it!!!
what may start off as bad soldering will quickly become extraordinary soldering with a few hours of practice. Soldering isn't difficult once you learn the correct methods and have good tools.
Don't be scared , practise on an old , broken radios , TV , etc ! It's more easy cos is not board soldering for what I hawe still no guts ! I will recomend Y to use Silver based soldering wire , (for better and cleaner contact , with less corosion ) plus if Y can find , to be filled with cleaning cemical , inside , or if can't , use a quality paste to put on contacts , soldering iron ,etc , before Y start with contacting parts ( melting down soldering wire ) ! Ask a pro for recomandation , wich power of a soldering pen is gona suite Y ! Enjoy in future projects !
I love the MojoTone Amp Kits,they have the best of every thing you'll need in your dream Amp!The 1959 100 watt Plexi British Amp "TUBE" is the very best you can ever use!My 14 year old son and my and my self have been working on our second tube amp now,and the results are unreal.To even consideration to purchase such an Marshall Tube Amp would be in excess of 5 to 10 thousand dollars!I know there are critics out there that saying,OH NO!A fact though.
@TubeDepotTV I'd be "road testing" those every moment of spare time I had! And building them, and testing them, and modifying, and enjoying the amazing tones that only a true vintage style amplifier can provide.
Great Video , Thanks , Most tech guys act like they are secret scientists or some shit , Luckily Guys like you show the love and know how to help others.
Oh hell yes! Great googalamoogala! This is the one that sounds like God shouting from the mountaintop! Many of us in the over 50 camp think of these as the "Allman Brother" Marshalls, violin-like sustain for days, killer for slide (brother Duane), goes with a Les Paul like beer goes with pizza! Who the hell needs pedals? Only 1 down side, grumpy grouches will be screaming "TURN IT DOWN" constantly.Not recommended for apartment dwellers or small beer joint gigs. A truly awe inspiring amp!
@TubeDepotTV Very true. If I was building the amp I would try and be as true as possible to the original tube compliment. KT66 tubes just have such a unique tone. Many people don't know this but the KT66 was a big part of Jimi Hendrix's sound. More bass than an EL34, more mids than a 6L6. Ton's of headroom, a good example being the Monterey Pop festival songs.
Hey Rob, try using nut drivers instead of pliers or an adjustable wrench to tighten the nuts on the front panel switches and pots. Nut drivers fit the nuts securely, won't slip, and have a smooth surface so they won't scratch. Otherwise, very instructive video! Thanks, Greg.
Tube Depot, I love your videos, everytime I see one of your videos I imidiately get the urge to build one of your kits (specially this one ) but unfortunately my financial condition don't allow me to do so. I love your channel. You Guys Rock, Sincerely; Josh
Would it possible to have a demo of the amp. I know that there's one on RUclips but there's so much effects on it. I'd love to hear it - as the audio sample at the end of your video sound just great - and the difference when you play with the different parameters you added to the JTM45+. Anyway, thanks a lot for all your videos and for sharing your amp knowledge.
Where is the master volume in the signal chain? Does it turn the guitar signal down before the tubes or the output signal down after the tubes? If you pit the MV at 10, is that the same as a non-MV setup? May buy the kit this week. Haha
***** i would like to see you come out with a vintage style super lead ( hendrix style) with the 4 input jacks on the front. although this amp looks nice and im sure sounds nice that master volume instead of a 4th jack kinda blows it for me :(
+TubeDepot Great price for the your kit without breaking the bank, example I found a half for 1600 100watt, price of this kit I would have extra left over for a decent cabinet plus buy few pedals. Would you be coming out with a 100 watt kit that can switch between kt66, el34 and 6l6 tubes, resonance knob, master volume and a jose mod.
+DALE97DSM i disagree. for the price you could get a used genuine marshall. nothign against TD but if you can buy a genuine marshall combo amp for 600 to 700 ( and that is new) why spend almost a grand on the TD one? if you can get a used marshall head for 600 to 800 why get the td head kit? i always wanted one of the kits but the lack of funds and price compared to a genuine marshall just doesnt justify it.
+lordraptor11 while it is true that marshall has some excellent tube amps and amp heads in that price range, but if you want a marshall reissue of a jtm45 head it'll run you about $2000 @ guitar center and if you want a jtm 45 combo the closest thing currently offered is the blues breaker reissue (which isn't exactly the same, 2 x 12 speakers, 30 watts instead of 45, and with a tremolo ). compared to these amps you do save building a kit from tubedepot. But you have a point that alot of people figure that a DSL40C would be close enough for less money. personally I'm building the jtm45 combo.
Hi, I don't know if you have answered this already, but is there a full assembly video of the amp? Would be very interesting! Anyway very nice work and sound of course!!
A Twin Reverb with a master volume, foot switchable channel boost, and buffered effects loop is on my bucket list for DIY builds. There are some incredible tweaks and channel mods floating around online from some amazing amp builders. One day...😁
Is it "hot" enough as is? Or would it make sense to maybe add a one-wire mod... maybe through a switch so it could be turned off again? Would love to get more sound bites.
Hi guys ! Your work looks formidably neat ! On the other hand, I'm building a '59 Fender Bassman model 5F6 and was thinking about doing some modifications (I'm aware that a JTM45 and Fender bassman are quite identical in some aspects): 1- Changing to a solid state rectifier 2- Inserting an effects loop 1- If I do this, should I change some capacitors values in the rectifying section for bigger ones ?? (I mean with more capacity) 2- I've heard that this might be a waste of time in a fender bassman because the difference in tone wouldn't be that noticable... And as a valve state amp, matching the impedances would be quite troublesome and I would have to design some buffer to lower the impedances and back. Anyway, I'm an amateur on this, what would you recommend ? Thanks for your time!
I'm very interested in a low watt version with effects loop and reverb... I'd love to build one myself... but i have no experience with any of this. But i'm a tube loving fool!...
Just to be safe, take a 1 watt 1K ohm resistor. Solder it to two pieces of stranded wire. One piece on each lead. One the ends of the wire put an alligator clip. Clip the resistor between a filter cap. (These are the big can caps right off the diodes or rectifier tube) Clip onto the + terminal of the first filter cap into the circuit. Then clip the other end to the ground. Always wait 3 -5 minutes after an amp is turned off to touch anything. This R jumper will bleed any stored charges. :-)
@TubeDepotTV My point was that just because the Marshalls used the EL34, the EL34's we not the reason that the amps were failing so much. And if you've got the time, what's your opinion on the new Tung-Sol KT120? Good, bad, crazy stupid?
@TubeDepotTV I think it's a little bogus that the american distributors were putting 6550 tubes into the amps just because there was a "high failure rate". But I quote Ritchie Fleigler "These things were not used to play surf music!"
This is a really informative video. My only question is, since it's Tube Depot, shouldn't you have shown the tube compliment and install? Not critizing, just asking. There's a lot of good stuff in this video and worth watching again.
I wish you would build me a fender tonemaster, I owned one and my amp tech said that looking inside it was a work of art.... or a twin reverb without a printed circuit board, the old fashioned way, unlike the modern clones.
I'm Thinking of buying this kit but there's no sound bites anywhere. I assume with 5150 in your tag you would know. Will it get that 78 Brown Sound. Will it clean up nicely when you roll the volume down on the guitar?
I love the way this sounds cranked. Pure awesomeness. I have never built an amp before but have a little experience with working with electronics. Which build would you suggest for a beginner? Thanks!
What software is being used in the background for the layout of the amp? I've always been curious. It seems very helpful. Especially in the case of making the board.
Do you have specs in the kit to build it without the master volume, and other added controls? I'd prefer to keep it as close to an actual JTM 45 as possible.
Im very interested in this amp but cannot find any videos other than this one showing the tones. The only other one has the guy running effects pedals which defeats hearing the amp
dear tube depot how much roughlly will it cost to buy and send a jtm45 head kit to scotland including taxes etc etc , ps, what a beautiful jobyou guys did on the build , sounds amazing too plz anz back , many thanks!!!
Hello, you are a master of the amps ... first of all this is a translation since I do not know English I am Spanish sorry..I have a question I want to mount a 6n2p and a pcl86 to make a 6w on a vintage radio chassis but I have a doubt about the mass ... gnd .... and the chassis..I do not know whether to make the chassis driver with gnd ... and if that is how I do it ... I connect all the points of mass to a single point ... it can be done in several ... or only the potentiometers and jacks go.
Gee, this is right up my alley. Maybe I could even but a set of new caps for my Magnatone. I'll just click the hyperlink here on the video page... Hmm, you'd think it would be more prominent... Maybe it's on the Google+ page... Hmm, maybe they just make these great videos and never sell anything.
Awesome Video,I would so buy the kits if i aint broke, haha. I was thinking,would it possible to make some videos on how to mod the kits you sell,using the components you provide.
Thanx, I'd mainly do guitar maintenance works... ( potentiometers, switch, pickups, groundings). How many watts should the iron station be? 30,40w or higher. A good brand for that ( long lasting) Thanx
for PC board work and general wiring, a 25W iron is excellent. However it may not have sufficient thermal mass for larger soldering jobs. A 40W iron is better for soldering to the back of pots and to terminals but the heat from these irons could potentially damage components and melt insulation. Better to have either one of each iron, specialized for the job at hand, or purchase a temperature controlled soldering station. The single wattage irons run around $30 a piece. A temp. controlled station runs about $100 (well worth the money if you solder regularly).

I love how he just runs his hand over the knobs and puts everything at 10.
He surfs.
That's how Randy Bachman (BTO) did it with his Sunn Model T's every gig.
Dude dimed. Every knob....love it..

My god where has this channel been all my life
And why haven’t they updated with new amp builds lately?!?!
Disregard last post about finding the right kit. This it it! Awesome!
This is my kind of father and son project… Keep on rockin
These vids make me want to start soldering and building amps :) even if I can only make bad soldering :)
what may start off as bad soldering will quickly become extraordinary soldering with a few hours of practice. Soldering isn't difficult once you learn the correct methods and have good tools.
Don't be scared , practise on an old , broken radios , TV , etc ! It's more easy cos is not board soldering for what I hawe still no guts !

thanx so much :D
Nice video. It takes me back to the days of my youth in the 1950s when I scratch built a lot of my Ham Radio equipment. Thanks for sharing.
Rob Hull! You are the MAN!
Great to see you're back guys!

I have been watching this video for the last six months and i cannot wait to gather some money to buy the kit and make the amp myself!
Love the nuanced control adjustment . Dime It.
@TubeDepotTV I'd be "road testing" those every moment of spare time I had! And building them, and testing them, and modifying, and enjoying the amazing tones that only a true vintage style amplifier can provide.
Great Video , Thanks , Most tech guys act like they are secret scientists or some shit , Luckily Guys like you show the love and know how to help others.
This video is so satisfying!
Great demo !!.........Thank you guys!
that amp sounds incredible
Very nice job guys. Im actually building an 18 watt self-biased amplifier at the moment and this is great to watch!
Great video and very informative. I love the roll of the knobs at the end.
@TableWolfMusic I was talking about effects pedals. And I too, have a deep desire for a TubeDepot amplifier kit!
Oh hell yes! Great googalamoogala! This is the one that sounds like God shouting from the mountaintop!

In my experience just tightening the driver by hand (without a ratchet) is also just the right amount of tight ...
Fantastic sound.
Your wiring and assembly is beautiful!
This was a lot of fun to watch. I'd really like to try building a head sometime soon.
Tube Depot, I love your videos, everytime I see one of your videos I imidiately get the urge to build one of your kits (specially this one ) but unfortunately my financial condition don't allow me to do so. I love your channel. You Guys Rock, Sincerely; Josh
Very slick amp, exactly what i am looking for. To bad i don't have the space or tools to accomplish building one. Very good video.
best video I've seen in forever!
Thanks, great video!
I got a used Mesa Boogie Nomad 100. The tubes are from Tube Depot! Sounds great.
I always pre-solder the input sockets at the outside of the amp. After completion, remove the whole assembly and re-install in the inside
What fun! Thanks for sharing.
Can you do video on building a vintage AC30/6 TB complete with Vibrato and Tremolo? I'd be thrilled!!
You're doing an amazing work ! Thank you very much for the tutorials !
Thanks. This is some quality knowledge!
Great vid! Very interesting. yeah, the ole western shootout scene. hahaha
can you tell me the cost of the kit? Just curious.
I´m waiting exactly for that!!! Please please do it!!
I wish more than anything that you guys offered a video (and kit) on installing an optional FX loop. That would be so amazing.
Great video and great sounding amp! I imagine that the voicing of the amp on the board is another project altogether.
Well done, great compliments ...
I was wondering which ones could I use... Thanks so much!!!
I wish you would make some videos really showing how your kits sound.I would like to hear more before buying.Thanks
raytheprinter i can tell you right now even without using them, that these are of great performance
fastest amp to dial in on the planet! I love the hand swipe to max her out! lol
My little children after this video began to play the game - "Who will play first? (Clap-clap-clap!!!)" =) Thank's for all videos))
You guys make it look so easy. Great work! I plan to get this kit at some point. My biggest fear is screwing something up though.
Would it possible to have a demo of the amp. I know that there's one on RUclips but there's so much effects on it.

You guys just built and totally nailed Marshall's greatest amp (a Fender copy nonetheless)
Keep goin (y)
I think about a hot-rodded plexi kit all the time ...
***** i would like to see you come out with a vintage style super lead ( hendrix style) with the 4 input jacks on the front. although this amp looks nice and im sure sounds nice that master volume instead of a 4th jack kinda blows it for me :(

You guys should do a video showing the tones
Now that was very interesting, i loved the rock paper scissors at the end, LOL
jesus, this amp sounds like a beast!
I would love to learn how to build my own 2 channel, twin reverb combo amp with effects loop.
A Twin Reverb with a master volume, foot switchable channel boost, and buffered effects loop is on my bucket list for DIY builds. There are some incredible tweaks and channel mods floating around online from some amazing amp builders. One day...😁
Oh man this is awesome!!! I want one!!! :)
Is it "hot" enough as is? Or would it make sense to maybe add a one-wire mod... maybe through a switch so it could be turned off again?
Would love to get more sound bites.
excelente, very nice work
Is a full length version of the build available?
OCDs about some wires inside but eyeballs switch holes on the outside... why not measure the locations before inserting the other components?
Hi guys ! Your work looks formidably neat !

Such neat wiring and attention to detail - truly excellent! So, when are you going to build a Marshall Major copy...?
Best channel Ever!
Herber, you are fantastic. Thanks for the great comment.
r u sure?
this is awesome
Just to be safe, take a 1 watt 1K ohm resistor. Solder it to two pieces of stranded wire. One piece on each lead. One the ends of the wire put an alligator clip. Clip the resistor between a filter cap. (These are the big can caps right off the diodes or rectifier tube) Clip onto the + terminal of the first filter cap into the circuit. Then clip the other end to the ground. Always wait 3 -5 minutes after an amp is turned off to touch anything. This R jumper will bleed any stored charges. :-)
The solder connections to the pot. bodies look like they might be cold. You might try using paste flux if that's a problem.
holy crap that's awesome!
@TubeDepotTV My point was that just because the Marshalls used the EL34, the EL34's we not the reason that the amps were failing so much. And if you've got the time, what's your opinion on the new Tung-Sol KT120? Good, bad, crazy stupid?
Inspiring, I wish i had the tools.
@TubeDepotTV I think it's a little bogus that the american distributors were putting 6550 tubes into the amps just because there was a "high failure rate". But I quote Ritchie Fleigler "These things were not used to play surf music!"
This is a really informative video. My only question is, since it's Tube Depot, shouldn't you have shown the tube compliment and install? Not critizing, just asking. There's a lot of good stuff in this video and worth watching again.

Nice build..14:52..man you are speedy!
I built These things back in the sixties, since then i´ve moved on a bit. Semiconductors will do the Job very well too
I'm Thinking of buying this kit but there's no sound bites anywhere. I assume with 5150 in your tag you would know. Will it get that 78 Brown Sound. Will it clean up nicely when you roll the volume down on the guitar?
Yo this is sick!
I love the way this sounds cranked. Pure awesomeness. I have never built an amp before but have a little experience with working with electronics. Which build would you suggest for a beginner? Thanks!
Dudes!! Great job!!
Just a question... What's the power rating of the pots?
What software is being used in the background for the layout of the amp? I've always been curious. It seems very helpful. Especially in the case of making the board.
Mynor Gonzalez - Inkscape
Let me know when you release a kit to build a 1962 Bluesbreaker amp.
The overdrive in the end of the video is just the amp? Thank you
Do you have specs in the kit to build it without the master volume, and other added controls? I'd prefer to keep it as close to an actual JTM 45 as possible.
And what about power ratings of speakers?
Should I just go with circa two times the output of my amp, or should I get even higher rated ones?
Im very interested in this amp but cannot find any videos other than this one showing the tones. The only other one has the guy running effects pedals which defeats hearing the amp
Great video. Hi, which name yellow tool clears the edge of the hole?
Sweet!
Will these work in europe with 220 volts?
dear tube depot how much roughlly will it cost to buy and send a jtm45 head kit to scotland including taxes etc etc , ps, what a beautiful jobyou guys did on the build , sounds amazing too plz anz back , many thanks!!!
Hello, you are a master of the amps ... first of all this is a translation since I do not know English I am Spanish sorry..I have a question I want to mount a 6n2p and a pcl86 to make a 6w on a vintage radio chassis but I have a doubt about the mass ... gnd .... and the chassis..I do not know whether to make the chassis driver with gnd ... and if that is how I do it ... I connect all the points of mass to a single point ... it can be done in several ... or only the potentiometers and jacks go.
wow!! awesome! What is the feedback switch for???
Is the master volume you added a post phase inverter master volume?
Gee, this is right up my alley. Maybe I could even but a set of new caps for my Magnatone. I'll just click the hyperlink here on the video page... Hmm, you'd think it would be more prominent... Maybe it's on the Google+ page... Hmm, maybe they just make these great videos and never sell anything.
Craig Wheeler You're right, that is an issue! The links have been added into the description.
Sounds exactly like my 80’s Peavey Bandit.
Awesome Video,I would so buy the kits if i aint broke, haha. I was thinking,would it possible to make some videos on how to mod the kits you sell,using the components you provide.
best amp ever !
This channel is awesome why am I 6 years late?
Thanx, I'd mainly do guitar maintenance works... ( potentiometers, switch, pickups, groundings).
How many watts should the iron station be? 30,40w or higher.
A good brand for that ( long lasting)
Thanx
for PC board work and general wiring, a 25W iron is excellent. However it may not have sufficient thermal mass for larger soldering jobs. A 40W iron is better for soldering to the back of pots and to terminals but the heat from these irons could potentially damage components and melt insulation. Better to have either one of each iron, specialized for the job at hand, or purchase a temperature controlled soldering station. The single wattage irons run around $30 a piece. A temp. controlled station runs about $100 (well worth the money if you solder regularly).
