Great video!! I just discovered a wonderfully dusty 1959 Champ 5F1 in a corner of a neighbor's home and am going to help him sell it. The amp is 100% factory original. This video was super helpful in giving me an idea of what it may need to go another 60+ years.
Just had to come back and rewatch this video after deciding to get inside my 5F1 and get rid of the tone webs. Glad I did as all the date codes inside confirm it's a 1957. Valves are Tung Sol & RCA, transformer is Triad. Thanks for the breakdown of the amp in video, it really helped me

Bwahahaha! Oh, god, THAT guy. 🤣 You gotta make sure you you're randomly walking along the river bank, then magically discover this laying there in the mud first though. 😅 Might as well paint all the caps & resistors red afterwards too! 😉
great amp! also, your commentary on this one reminded me of bob ross; especially with the brush haha. just need to add a happy little capacitor in there
Looks like one I left in my attic in 1990 !!! Didn’t know what I had then !! It was my dads he had as a kid and he died in 89. Left in attic In Charlotte nc. Hate it now !! 😩
Hi Brad, I have been watching g you and uncle Doug forever. I absolutely love your videos. Please don't ever stop doing your videos. You are amazing. This videos are entertaining and informative. Keep this great stuff coming. Thanks Michael Newell from Niagara Falls, Ontario, Canada
Hey Brad, good to be viewing your channel once again. I scored on a perfect 63 Tweed Champ 5F1 circuit, a few years back. Actually a bit cleaner than the one you are recapping. Got it for $800 bucks. By the way, love your comment you made a few days ago. I'm the one that lives in California, that has to put up with that crap.
When I was in high school, the janitor threw away 12 of those in the dumpster when the music department got new ones. My buddy and I tried to claim a few but we got caught and told we couldn't dumpster dive, we came back later that day and someone beat us to them 😢
That Zio has a bit of snarl in those single coils!!! Those old Tweeds make a single coil sound so sweet!!! Beautiful amp!!! To think I was 5 when that bad boy came out!!!
Nice video and nice amp :-) The good old tubes rarely die. My modified "Knutsen" amp still has the original '63 Telefunken EL84 pair and Telefunken ECC83 PI tube. The EL84s may have been stressed or even red-plating at some point as the original PI coupling caps were leaky, but they appear to work great.
Great vid. You seem to have mellowed a wee bit...good to see. In 1962 my dad made me an amp for the bass guitar I had built (aged 16) ..reminded me of that time. Post war austerity and ex military electronis...those were the days😊
beautiful amp Brad - only one comment on it that I would suggest. I know the traditional rule on amps has been same value or highter on the electrolytics - generally a true statement. But high value caps will rob some of the tweed tone from these amps. After all, that 22mfd electrolytic is 30% higher than the 16mfd. That will make a difference - the amp will have more capacity on reserve and be slightly stiffer. It makes a big difference on a relatively simple amp. It may make sense to increase on an amp that you want to be cleaner, but not one that you want to distort in the same manner as intended. You can get 16mfd caps.
Hey John. Normally, I might agree, but when's the last time you pulled a cap and it wasn't higher than the spec value anyway? I didn't measure the originals, but I'd be willing to bet they'd be closer in value to the new caps than the printed value, at least the two that weren't exploded. ;) Good to see you, by the way! You need to come up to Louisville and geek out on amps with me in a video sometime.
@@TheGuitologist I don't really understand the point - if something calls for a 16 mfd cap, and you put 22s in there - part of the sound of a tweed is that 16 mfd cap. 22 is a substantial difference than 16 (percentage wise). Tube amps are more about percentages as you know after years of swapping values. if you do that to multiple stages, you will definitely hear the difference. Maybe you didn't realize you can get 16s and 20s easily enough now. I am definitely am not slamming your work. You try it, and if you don't think it works - don't do it! But try it before you judge it. I used to do the same myself. Lots of good stuff. Right now am working a different job so I don't get to Louisville as often, but yes, I will stop by sometime and geek out over vintage amps and gear. Maybe if I have something interesting when I hit Louisville next I will bring it with me. It will be fun. Ha, I watched you repair a washing machine on a video today. I just did nearly exactly the same thing to my LG! We both value fixing things rather than spending a thousand bucks to replace it and unnecessarily filling up a landfills. Brad the recycler - the environmentalist. I've fixed my TVs, computers, and HIFIs too (when I am able). And one of my favorite guitars I purchased in pieces and glued it back together (it was likely ran over or crushed in shipping and was being sold as parts). It now looks pretty good but plays very amazingly well! TTYL
Man, what a rad lil amp! Super nice shape. I'd be trying to hang on to that one, if I were you. ;) Loved hearing "Fearless" too.. Haven't heard that tune in a long time. Gonna have to give some Floyd a listen now! ✌️
I have a handmade Champ that i got a couple years back, never been a Fender guy, i'm all about distortion, but man, i really liked the sound of that amp. Need to send it to repair, i believe the power transformer gave up for some reason.
Nice work, Brad. First time I've seen old caps get re-stuffed like that. I have some old radios I'm restoring, including a tweed Zenith Universal and I might try doing that with it when I re-cap it. Thanks for this enjoyable little trip back to 1962!
Saw you cleaning up that chrome chassis. I’ve discovered some great stuff called Never Dull. It’s cheap and at WalMart. Comes in a tin can and it is pre soaked cotton wads. Very gentle yet great cleaner for chrome abd bright metal. Will not scratch! I found it in the automotive cleaner section at WalMart. Works great on all guitar chrome parts, brass, alum etc.. Love your channel Brad. Waiting for you update on your legal issues! We support your fight. Been through that stuff myself!
What a nice little amp. I used to own an old black face Champ. Don't know if he was using a tweed or a black face, but they say Joe Walsh used a little Champ on those classic studio albums.
1965 My Cousin loaned me his Champ and Duo Sonic, I had it about a year and then he decided he wanted it back-with broken heart I returned his guitar and amp only to hear that about a year later his house got ripped off and good bye amp and guitar, both of the early 60's vintage.. I wouldn't mind another Champ, I gave my Daughter my Strat and Super Reverb (65 original) but still have a Strat and a Pignose, - believe it or not a Pignose is pretty good for bedroom playing.
1960 was the dividing line between the tweed amps and more modern imitation leather. 5 series circuits as shown here were replaced by 6 series during the same year. Since Fender was a tightly run company, some of the sample materials brought in for the decade change were used up resulting in some rare color combinations in 1960. Prebuilt chassis from the previous era were also updated with new designation written on the old tag. In this case the '4C' may actually be an 'HC' since date codes of the era consisted of letters. With a date of 1958 March, the tweed and 5 series circuit makes more sense. Except for the blue capacitors which replaced the less reliable yellow variety if the 50's. These would be closer to 1963. Perhaps old pre build stock which was assembled late enough to benefit from better capacitors.
Great video! Wanted to know if you were interested in fixing and modding a Ross Flanger Distortion effect. It defaults to white noise after about 10 minutes...also wanted to be able to put a option switch for flanger before or after distortion.
Just a question... When you mentioned the speaker was tired and needed a recone, the suspension getting weak, or something with the voice coil? And how do tell? Thanks for a cool video.
Even though it isn't being done to deceive, re-stuffing caps doesn't make sense to me, I'd rather see what the caps actually are. But I can understand guys like you amp techs who see vintage amps often, and want to see those vintage cap covers just "looks right". Jupiters look fine to me!
I make modern copys in head form lol, right now experimenting with adding a bypassable gain stage using a 6829 and 6DJ8 in the preamp and 6P1P-EV for the power amp same core 5f1 circuit with a few add ons and a diode rectifier using some diodes from an old organ, power transformer is extremely small so diode rectifier is needed if i wanna pull off a 2nd twin triode.
I'm really glad this video does not have the scratch-and-sniff feature with that being said LOL that thing is in pretty good shape that's nice it would be so cool to leave the original cast Andre stuff that would be so cool evenly some of the the bad part
Sir that’s so Beautiful those vintage Tweeds amps I Love , and your work you do Excellence well done Pride , as you were saying you should own that one ! Gorgeous. Peace respect.
No one is gonna mention the weapon haha ? I love it how it lays next to you until it somehow dissapears around 32:55. Germans going crazy :D BTW @The Guitologist found your Channel a few days ago and i love it. You do a great Job and its just a pleasure to watch you !
Okay I'm going to say something the organ industry was way better at building then any of the guitar factories that's why it's so easy to make them badass
Absolutely! I think Uncle Doug already did. I forget which amp and which video, but yeah, it's totally doable and would be a lot cheaper. There's kits, but sourcing all parts yourself would be cool. Transformers would be the most expensive part.
Interesting. The dates would definitely fit this being a 5f1, as did your tube label. But. The 25uf bypass cap across the first stage of v1 is more in line with the 5e1 circuit -or- fender had a misprint in the schematic that went unnoticed for half a century
Glad to see the old Brad back and repairing amps KOOL
Funny how most people only care if it works and what it sounds like. Only electronics people care about looks and originality. Great job my man.

"Tone Webs" LOL Dude, you crack me up.
Now people can argue which webs have the best tone. :D
@@DChrls Yeah, I'm pretty sure it's either gonna be the Violin or the Black Widow

Uncle Doug stuff some capacitors by using dowel wood with the tiny capacitor on the inside LOL it look great when he got done though

I own the Fender 57 Champ amp reissue I believe from 2008 !
As much as I'm a fan of the old Silvertones, I swear those tweed Fenders are just monsters. Thanks Brad.

Popped pokniio 🎉pi too Ii 😅🎉🎉 kk pb boo off
Nice to see another oldie on the bench..! Great job, and nice playing..Ed..UK..😁

When I got mine I used an encapsulating liquid on the asbestos that they had on the rear cover of the amp.

You have to hand it Leo for designing something to be loud and in as small a package as possible. He definitely had giging players in mind.
Thanks Brad, You are Absolutely Correct About Tubes!!
Tubes last Way Longer than any Music Equipment Store tells ya.
UD did a 'stuff job' on one of his projects with the original electrolytic caps as per customer request....he did a great job on it !
You're killing me, man. Now I have to figure out how to play 'Fearless'.
Man, what a rad lil amp! Super nice shape. I'd be trying to hang on to that one, if I were you. ;)
Loved hearing "Fearless" too.. Haven't heard that tune in a long time. Gonna have to give some Floyd a listen now! ✌️
heyyyyy fearless!! that was cool. just saw roger in atlanta! first time seeing any of them
Your making Uncle Doug real proud stuffing those caps :)
Re-stuffing cool looking caps is a great idea!
Definitely sounds better than my 1980 Champ!

A dream amp. Cool content indeed.
I'd love to hear a strat thru that thing. I loved the old Floyd, my friend.
Me too, I really want to build an amp like this, and also a tweed bassman for my strat.
I just took the original tubes out of my 1973 Traynor YBA-1. the preamp ones anyway... 2 were microphonic. I'll keep them. Not bad for 48 years old
What a nice little amp. I used to own an old black face Champ. Don't know if he was using a tweed or a black face, but they say Joe Walsh used a little Champ on those classic studio albums.
One of the best amps ever!
Did I just hear some old Meddle era Pink Floyd (A Pillow Of Wind)? Whtever one that had "You'll Never Walk Alone" at the end...You're the best.
The song is "Fearless" off of "Meddle"
Nice lacquered tweed..I have a 61 Princeton tremolo in brown Rolex cream knobs
Love the random gun on the table
Oh no, no more wolly bully. Looks good Brad. Nice to see your back. Cheers
“See, Honey - it’s not hoarding. Brad The Guitologist told me to save them.”
Finally someone I agree with on amp repair.
Nice video, glad you are making these types of videos.
Now all that amp needs is a Weber speaker. :)
Loved that old Pink Floyd 🎸
Bluesky, boss DM2-w, preamp is all you’d need with this…good review
Would have to recap it anyways, plus the addition of the elevated AC from the wall outlets we run these days

Great work & vid, Brad! Amp sounds awesome, I always like a slightly damaged cone for it's "hanging onto life" sound. Worth envy!!
