Colleen, your 3-wire installation approach is spot on. The only improvement you can make is when sizing the three conductors coming out of the AC supply cable. It adds a margin of safety to strip about 8" of cable jacket, and then shorten the hot and neutral wires to 4" long. This creates 4" of extra length of ground wire in the chassis. The reason for this is if the AC cable is somehow yanked hard, the hot and neutrals will break before the ground does. This can prevent the chassis from becoming live at mains voltage. I've been told that it's 'extra work' to do this, but any little increase in user safety is good.
I've heard of this too!
There's something about watching people doing amp repair that I find very calming.
ASMR
It's her voice that's also very calming!
Her, because she’s enjoying what she is doing. Not complaining every 10 seconds like other repair people/channels
@@timpit164 Haha! I wonder who you mean? 🧐 I watched hours of that guy, but dropped when he started trying to feud with Beato (for views), then went all political. I come here to get away from all that.
Her sweet voice alone can fix any amp 🥰
Nice to see a young person full of enthusiasm and knowledge of these old amps. Nice relaxed presentation style too. Keep it up 👍🏻😎
you have such a nice calming soothing voice ......................music to the ears!!!
Sorta hard to be stressed out hearing her thoughts on approach, and her work. It’s like high voltage yoga.
I love How her workplace actually looks like a functional everyday workstation rather than something Out of a catalogue.
I was an electrical technician in the military for 22 years. You are regularly teaching me things about amp circuits. I wish you decades of success and growth.
you make a good bch

Explaining the how and why/theory is really helpful and cool.
Agreed. I especially like the drawn diagrams. I didn't really understand how a chorus pedal worked until recently when a buddy drew me a picture on a napkin showing the signal entering the pedal as one wave, splitting into two waves, one dry and one modulated and then exiting the pedal as a combination of the two waves. I guess I'm a visual learner.
I too have a '56 White that I found in a pawn shop in the early ' 90s for $17. It had a hang tag that said 'As is'. I turned it around and noticed that the power tube was just rolling around in the bottom of the cabinet. Anyway, I bought it, got it home, plugged the tube in, and VOILA, it sounded great! I still play it to this day. I love your videos, how they're so informative, and how you don't cut any corners. Nice work, and please keep making them!
Hi Colleen. I’m an electrical engineer from London and your 100% correct the way you have connected the mains lead in this video. There is fantastic content is your videos and I thoroughly enjoy watching your repairs.
The way you rewired the fuse make sense. Thank you!!!
Been doing repairs for 18 years and I have seen a lot of things in my time. It takes a certain type of person and mindset to do this type of thing and you definitely have what it takes. Great videos keep em coming!
Well done! I do agree that a full replacement of all capacitors are in order for a unit of that age. That being said, I highly commend you for communicating with the owner; and fulfilling his wishes. It really demonstrates your integrity as a tech. I look forward to your next episode with great eagerness.
Only since you asked.. the proper way is to wire to the switch first, then to the fuse. The reason for this is if someone grabs the fuse without the amp being unplugged the fuse is still live. This way, with the power switch off, there is no power to the fuse for sure. That's how it was explained to me
PS. Love how you show the actual soldering repairs!..For some reason I can watch someone solder all day. I guess that's why I like amp building so much, it's relaxing.. :)
Agreed
Never replace a fuse in a plugged in device. Never.
Your presentation is detailed and informative. The amplifier (white) has an interesting story. 🎸🤘👍
Where were you 35 years ago when I had a Gibson GA 300 that needed to be rebuilt.Thanks for letting us hang out, Keep up the great work..😁😁
Channeling your "inner Uncle Doug" with the notepad! I like how you've modernized the approach with a pen instead of pencil!
Ezra, with a pencil, if you're wrong, you can correct the error.....and then deny it ;)
I have literally never seen anything on these in real life. Only a picture in a fender book. Fascinating
Thank you for explaining what the death cap is. I see people talking about it but never have said why they call it that
Now I need to check my old Gibson amp to make sure it doesn’t have one!
What was the original purpose of putting this cap in??? Why is it no big deal to remove it? Thanks
@@altadena57 I think you have to do it when you have a 2 prong cable because it prevents you from getting shocked but the problem is if it decays, you can. No need with grounded three prong plug.
@@TK-fk4po Ahhh; now I get it; Thanks much
@@TK-fk4po Thanks for that explanation.
So happy to see someone that makes a mechanical connection before soldering and doesn't blow on it to cool down faster.
I just found your channel a few days ago and i love it!!!!
Wow !- finally a girl doing one of my favourite activities! Repairing electronic equipment - especially really old one - is one of the most satisfying activities for me. You are doing this very professionally and thoughtful - gratulations!
Your videos are excellent! when I want to keep the "original" look of an old tube radio, I empty the old caps and put the new ones in the tubes of the old ones...I know it's cheating...but I like it! Bravo!!
Hey thanks so much for the shout out Colleen. You are the COOLEST! I just sold my White amp, i miss it already.
If there was an Emmy for square shootin' righteous content uncle Doug and Colleen would have to share the honors, therapeutically well done.
Pleasure to repair such the kind of equipment. Every part is big enough and noticeable. No unknown smd components
I like it when techs change original parts out for servicing. It makes the amps less desirable to collectors, which is good for people who buy them and actually intend to use the things.
It's good to watch new techs to this ever growing topic..this is a capacitor. This is a tube...now this could be a Pento or a tridode valve..let's not forget current and voltages that need to be worked out when building or restoring valve amps.
Keep up the learner thumbs up.
Just so amazing, God Bless and Protect you!!!
Been at this 59 years and never heard of "White" amps. Hopefully, we learn something new every day!
Your videos are so fun to watch, it takes me back to when I was studying audio engineering building preamps I forgot how fulfilling doing repair/build work could be. Thanks can’t wait to see more!
SO So So nice to see a BEAUTIFUL young lady fixing amps instead of the crotchety old men that usually do. Thanks for your videos!!, A plus is that cool smooth voice you have too!!! AWESOME!!
P.S. I love watching Uncle Doug also ! I sure wish he had been my algebra teacher !
Thanks, Enid :)
Really nice job and the amp has that cool old 50s grungy sound
I have just found your channel, very interesting and well presented and with your recommendation I’ve also started to watch Uncle Doug. A nice job on the white amp, I agree with the way you went about the repair, keeping it as original as possible. The way you replaced the power lead makes sense to me and that’s how I think it should be done, great work keep posting.
At 4:30, the "death cap" does not need to completely short-circuit in order to put dangerous voltage on the chassis ---- they are often sufficiently "leaky" electrically to energize the chassis and shock you if one hand is on the guitar strings and the other touches a grounded object (or if you are standing barefoot on a concrete slab ---- pure danger! Even damp slippers can conduct to concrete; I found this out the hard way as a kid). I often plug newly acquired amplifiers into a ground fault circuit interrupter (GFCI) wall outlet of the type usually found in modern kitchens and bathrooms, and if the death cap is bad it will probably trip the breaker built into the outlet. Always best to add a grounded power cord and remove that capacitor; if somebody insists on keeping that circuit as original as possible, then at the very least one should convert to a polarized AC plug and ensure that the death cap is connected from the neutral line of the power cord to the chassis and not from the hot to the chassis. "Ground polarity" switching should ideally be bypassed, but if the customer insist on keeping it active then the death cap should be replaced with a modern "XY" safety capacitor, which are typically rated for a 1000 volts or more.
Just an informative educational channel. Love all the history that is shared.
I had to turn CC on to be sure ..."death cap" ...love it :)
Btw, totally agree with your power rewiring circuit: FUSE ALWAYS FIRST, PERIOD!
Nice clean work. And I like how you explain everything.
I have a 65 Fender Deluxe Reissue that has a slight issue, I'd love to be more informed, Im addicted to Amp Repair Videos now :-) especially old Fenders or AC30's . . Great Work
Nice to see someone doing soldering correctly, melting it onto the joint rather than carrying it on the iron.
I don't work on guitar amps, but you did the 120V AC wiring correctly. That's the safest way to wire it.

Thank you Colleen once again!!!
Always so much info in your repair videos!
I learn every time I watch your channel!
Thanks for the excellent explanation theory wise on how you solder in the 3 prong power chord with the fuse ultimately providing protection if the switch was to short out and fail.
I really appreciate your Channel Colleen!
I really dig your playing at the end as well! Regae/ blues/ Rory!

You asked about how others do a three wire cord replacement - asking like you just did. I would try to get a piece of heat shrink around the terminal where it joins the fuse input if I can, just because I can, for additional safety of us techs.
You do nice work! The chassis looks identical to my Princeton ('56) that I've had since 1988. I've rehabbed it completely and I'll never part with it.
They way you've done this job, it looks like you could change it all back to totally stock original if some collector fanatic wanted to buy it for insane money and put it in a museum. I hope you saved all the old parts and 2 prong cord.
My own personal goal is always to have a great sounding, reliable amp. But some people are nuts about that other stuff.
Very nicely done!
I completely agree with the way you installed to power cord. That's how I do it too. I also totally get the owner wanting to preserve the originality of a rare vintage piece of history. Keep up the good work, I'm really enjoying your channel! ❤😍
(I really need to start making videos of my repairs)
Great video! The most amazing thing is how technology evolved, which can be seen in the size difference between the older and the modern filter caps.
Regarding the death cap, have you ever considered using a Y capacitor? They are intended to fail open and are used in power supplies everywhere.
Beautiful warm sound !
Colleen, you absolutely rock! You have a beautiful way of thoroughly explaining what you are doing and why? Your God given, soothing timbred vox is also a big plus. Love your 'less is more,' & 'if it ain't broke, then don't fix' approach. These are TLC units, and there is a balance as to the original parts relationship to one another; All modern parts sound different than the old ones and I just don't get why? But all the way down the line from mics to phono cartridges, you will find that vintage audio equipment, speaks a much better clear and present language. Cheers!😊
OMG - I knew a guy here in Britain who would fly to America, buy an old car and drive across the states. He visited Chess studios and this old black guy sat outside loved his knowledge of music so took him to a garage and gave him some stuff. He had a 'White' amp that at the motel took half an hour to come on (as a valve electronics guy myself my head was screaming "NO!" when I heard this) but he said it crackled to life and had *THE* Chess tone he'd heard on his records since childhood.
Chess records is an national treasure
Amazing channel, love watching your videos. Please keep up the great work.
I install 3-wire power cords the same way you do except I like to solder the ground wire to the chassis.
I'm sure its fine being held by the power transformer nut the way you do it, but a solid connection makes me feel good.
I use the same grounding scheme when doing the u-ground plug mod to vintage amps. When building an amp, I use a dedicated screw terminal that I like to solder to the chassis as well. And I'll admit that I'd never heard of White amplifiers until today. Cool project!
This channel has potential to blow
-21rst of april 2021
Colleen you should check you bias on your 6V6. We're up to 122 volts AC now. You might be running too hot on 470 ohms. Might need to bump it up. It will save the tube and make it last longer
this is the best sounding amp youve done so far...
Glad I found your channel! This is inspiring me to finally service my '65 Champ.
Your subscriber number went up super fast. Congrats, you are pretty dang cool.
Hi,
So happy to see a young person with knowledge to repair, and restore vintage valve equipment.
All strength to ya elbow gal!

Hi
Thanks for explaining about the death cap. Was always a mystery to me.
So now I can see all the grizzled amp techs offering free beer and pizza with any repair, just to compete with Colleen!
Wow. A rare amp. Uncle Doug must be very jealous!
If I'm building an amp, I do the wiring this way. If it's an old amp I leave it as the schematic says. Nice video.
Came here on a recommendation from Brad the Guitologist.
Seems that you're doing good work here, so I've subscribed ...
I agree, it were my amp, as long as it works I would only replace what is needed, when needed. It’s all about the mojo
GREAT WORK!!!On the filter and coupler caps-they are not broke-why fix it?Go to them when they fail.If they don't cause hum or noise,run cool-fine.
Love the ending of the video! So tasteful, thank you!
Wow never even heard of these!
These amps are truly hidden gems!
Hi Fluff!
I do the same but use a high wattage iron to solder the ground wire to chassis when possible - I think the white line was envisioned as an alternative for non fender dealers where a fender deaer was in town already -- like epiphone and gibson -- but it never went as far -- and yes a tribute to forrest from leo ...
Sounds great. Nice and quiet!
Definitely one of my faves..
Beautiful operation done by ditto tech 💐
No leaky caps??? That's what you call a unicorn! Great work
I’m skeptical of that. I have never seen filter caps survive that long whether the amp was played nightly or if it was sitting under the bed for 50 yrs. Hopefully they were actually tested and not just visually inspected. I have found plenty of caps that *looked* fine but were still shot.
Sure is kinda risky to leave so old caps in amps that will get use, but if owner is OK and knows what could happen, its his thing. They could last couple years or couple hours. He will see. Recap is when you want to have something that will not let you down. This is risky to bring to gig, without backup. At least IMO.
@@_-_Michael_-_ , adding an internal fuse or two would be a good idea and could save the transformer if a filter cap shorts out. The fuses can always be removed if the next owner finds them philosophically or historically objectionable...
@@HBSuccess she said she tested them in the video.
Yes added fuse is good idea.
They could test good now, but not in some time, with old caps they could go wrong any time, they were not designed to last this long, that is just how it is.
I thought of a thing in regards to your Instagram post of what you might do differently! First off masterfully done and so love your attention to detail. I aim to get more physical distance between the cathode bypass cap and the output section cathode resistor so it doesn’t cook the juices. Great call on the jacks. I might have been tempted to clean and keep but in retrospect it would have encouraged corrosion on the face panel which is much harder to replace! Such great work and thank you for posting real deal quality repair videos!
Man, I knew nothing about these amps. I sure would like to find one in a dusty garage somewhere 🤗 great video.
i want one of those real ones, it looks so cool. i based part of my janky 12w DIY class A transistor amp on the 5F2, the power amp is inductor loaded, and a nice zobel-network give it a vintage feel.
greetings from the Netherlands
Krikeys that amp sounds killer than most small amps out nowdays.!!!😮
Excellent video, Colleen, featuring an amp that I have heard of but never personally encountered. To greatly reduce the risk of damage due to retention of the original filter caps, the owner might want to use a current limiter while playing it. Current reduction would be negligible and the slight voltage reduction might actually be helpful. Thanks for posting :)
Thank you Uncle Doug! I always love hearing your feedback. Happy holidays ♥️
My pleasure, Colleen. Merry Christmas to you all :)@@FazioElectric
Awesome. I feel like it sounded better after you replaced the jacks. Kinda like how washing your car makes it drive better. :)
NO! NO! NO! Replace *ALL* OF THOSE CAPS! I DON'T know what your testing them with, BUT THERE BAD!!!!!!!!!!!!!!
Definitely a nice piece of history you had on your bench. Not wanting to risk the health of the vintage transformers, I would probably choose to replace all electrolytics (and the coupling capacitor to the output tube), vowing not to utilise wire cutters nor drilling holes. Given its rarity and value, the only alternative to me would be not repairing the amplifier at all and putting it underneath a glass jar. Though it would be a pity to leave such magnificent amp unheard. It sounded beautiful.
I wholeheartedly agree on your choice of wiring the primary circuit. Did the amp bias correctly with the stock 470 ohm resistor value?
Excellent video, enjoyed the walk through and explanations. Thanks for taking the time in creating your content
wish you were in our area. I have a Blue's JR MIM that just slowly died away when I was playing it. There are no amp techs that are in my area of 150 mile radius.
Thanks Faz. ⚓️. What’s amazing.... all the components are REALLY inexpensive < $5.00, except for good tubes ... great video, thanks.
The safest way is always the best choice. Good job!
Great job. I think the same about conection of the hot line in series whit fuse and the main switch. 👍
if the filter caps physically look fine and there is no his and hum or other strange ghost noises happening i would keep playing it with those filter caps too!
The camera loves you. I predict a bright future for your channel.
I install the upgrade 3-prong cord exactly the same way as you, including removing the death cap. Not sure, but I think that's what Red Rhodes used to do.
Imho the green ground should use a crimp connector as well as solder if that shorts it could melt the solder and lose it's purpose
What is the dissipation of that resistor 470 ohms, you have to pay attention to that because it can be seen that that resistor is touching the capacitor and that is not thermally correct placement. I am very happy with your channel and your videos are great, you could do more often I really enjoy listening and watching you.
Daaaaaaaaamn how awesome! You have such a cool job i wish i had you as my amp tech i like fender amps lol
Crapton hahaha -:)
That is so cool! 😎 Never heard of the White amps, but I love my 5F2-A build.
Bravo on NOT replacing caps that don’t need it. If the value is close and it’s not leaking, I think leaving them alone makes sense. Especially for preamp cathode bypass caps.
Curious can guitar output jacks be used in amp output jacks?
And have you ever heard of an output jack called pure tone. I use them on my guitar builds.
Some say it improves clarity with giving the chord another set of jaws for me it makes it just that
more secure. I am so enjoying your video’s glad you are on board.
Awesome job!
I have a 1953 Magnatone I would love for you to work on for me. It needs that same type of service.
The death cap should be replaces with a capacitor rated for this application. The old ones are funky.They will short from surges or spikes. Install 1 meg resistor can leak off the current if you want to just remove the death cap. . Always use a outlet tester before plugging in your equipment to ensure your outlet is wired properly or has a problem.
Agree. These caps are there to filter out noise spikes and high frequency EMI/ RFI from getting in and damaging the amp. The modern equivalent are known as Safety Capacitors. There are two different types. Class X are for line to line filtering only. They are allowed to fail short resulting in a blown fuse. Class Y are for line to chassis filtering and are designed to fail open. Note Class Y safety caps can be used in either. In this application it would make sense to use a Class Y2 given the Y2 option is rated for consumer applications.
Nice work! I really like how in these more recent videos you take a bit more time explaining things like the death cap and drawing up examples. Especially since you now have a bigger audience of people who may not know these things already. Me included haha.
Keep up the great work, excited to see more videos!
Never even heard of them! Awesome!
Your power cord configuration is 100% correct. Putting the power to the switch before the fuse, makes no sense. If you have a switch fault where the switch remains on somehow, or shorts out. Fuse can do nothing. Fuse always comes first.
That's my opinion anyway.
whats a good price for that Staco auto-transformer? I'm looking at a L1010VA, and they're asking $450. what do yo u think?
I appreciate your honesty in regards to the re-cap. At the end of the day, it's the customer's call. Not everything needs to be 100% road ready. It really depends on what they want to do with it and what it means to them. If I went to a guitar amp museum and saw a bunch of chassis's with F&T's in them, I'd be disappointed.
