champ

Hi folks! I just inherited a 1956 Fender Champ 5f1, untouched, original, with the 6" speaker. I had a tech go through for safety - had to change a few bad caps and added a grounded cord. The amp is amazing!!!! However, the speaker has some intermittent sizzle / static and either needs to be...

Well I finished my project. A Champ black face AA764. I modified the original schematic with some improvements. I added a middle pot and bright switch. The two bypass capacitor are 25uf and the 6v6 has a gridstopper and screen resistor with a 820ohms cathode bias resistor. The power transformer...

Hi, The Fender tone (sparkle on clean channel) bug recently bit. I'm mostly an acoustic guy (fingerpick, flatpick, blues, country, bluegrass, jazz). I have a Baja Tele and a Peavey Classic 30 (with a Dyn Comp, Joyo Vintage Overdrive, Joyo American Sound). But I want that Fender sound for when I...

Hi! There is a so-called "hand wired 5F1 Clone" on the local CL which is obviously NOT an exact copy as it has a tone knob, but I was wondering if anybody has seen anything that looks like this. https://austin.craigslist.org/msg/d/hand-wired-clone-tweed-champ/6530131891.html The seller started...

Hi all! After wanting one for a long time, I have my first tweed. Well, I am starting from the bottom, so it's a 5F1 clone :D I spotted this Mojotone 5F1 at a great price not too far from me. With the help of other TDPRI members and my tech I made sure the components were good, and I took the...

So, a while back I hit you guys up about building an amp for the first time. I took the advice here and built a Weber 5F1 Champ chassis. I'm going to turn it into a head, but I wanted to know what mods are out there for a Tweed Champ? Specifically for upping volume; but anything cool is always...

Hi all, Last week I bought a 1977 Vibro Champ in fairly good condition. The previous owner bought it back in 1977 and played it for a couple of years. After that he stored it until last month, when he decided to sell it. When I saw the ad, I knew the amp had been stored for quite some years...

I'm trying to conserve the thicker green wire that I got with my Mojotone 5f1 kit so I have enough to use it for the twisted filament wires. My questions are: 1) Why is it that the twisted filament wires are often routed behind the eyelet board, like in this picture...

I'm interested to know the difference, all else being equal, of swapping out a 5w output transformer for a 15w transformer. Does it actually increase the volume of the output, or is it just rated for maximum power? As in, it will be able to handle more headroom coming from the amp, but the same...

Quick question... does this amp in the back look to you like a Harvard, Champ, or another smaller tweed combo? Too small for a deluxe I think. If it’s the same one he used in the early 2000’s I know it has a 10-inch speaker. Never owned or played tweeds so unfamiliar with cabinet sizes.

Me and my father finally started to build tube amp. All soviet parts and some easy schematics like fender champ + modifications. Also I want to put in that box my favorite russian green muff. Don't know what we will get in the end, and that is most interesting part of it :) Bought some 1967...

I bought one of these amps in 2005 locally on craigslist. It was in unused condition. Only thing with it not being used much in 20 plus years is the caps need replaced. I took it to my amp tech and got it up and running. I had him add an adjustable bias so i can experiment with power tubes. I...

Until today, I had never owned, nor played through, a tube amp. I scored a '71 Champ this morning for an unbelievable price, so I took the plunge. After playing it for a day, I have one overwhelming impression -- the sustain on each of my guitars is suddenly through the roof. I mean, I...

Hi Gang, Well, here is the next stage in the saga of http://www.tdpri.com/threads/1965-fender-champ-low-output.712125/ After replacing the big can and the 3 electrolytic caps it was louder but still not full volume. I placed an order at Mouser to replace all of the capacitors that I didn't...

Greetings Gang, Well, my '65 Champ has loow output. Compared to my friends drip egde champ it's about 1/2 as loud and in no way pushes the speaker. I changed speakers, no change. Attached are pics from the inside, looks like every thing is original except for a secondary a/c line out...

A while ago I made the mistake of cranking my little champ 600 while playing through a EH Big Muff. After playing for a minute, I heard a pop and the amp just started playing screeching feedback. I noticed that the powertube was blown so I replaced that. I turned it on and it is still making...

Greetings all, Well in an attempt to quell my Kemper GAS I've gone back to the basics, today I went into my "vault" and took out my fenders. Guess I could sell the Princeton Reverb to buy a Kemper but 5 years down the line the Fender will be worth more and the Kemper will be obsolete and...

I brought out my 1973 SF Champ which I haven't played for two years now, plugged it in, turned it on and there was only a hum and some cracking sounds, no guitar sound - then the tubes got really hot and the 6v6 did even flash sometimes and suddenly I noticed a little smoke and the smell of...

Greetings from cold Helsinki! After playing for more than 20 years, I just recently found out that I really like the sound of preamp distortion of my Champ (Ceriatone Vibro Champ clone, Jensen C8R speaker, JJ ECC83S preamp tube): I played with my humbucker guitar (Yamaha SG-2000) and I...

Hi, I have been thinking in building an amp with two channels. Channel one would be a exactly the exact same circuit as de one in the fender champ, no tone control, just volume. Channel 2 would be the overdrive channel. Ising an additional 12ax7 and a tone stack. Volume on channel 1 would...

I have a SF Champ from 81 and it's all original! The tubes, speaker etc. Well, i want/need new tubes! These ones are glowing, and the 6v6 is almost blue if i hit a big chord at high volumes. My needs are more gain, more low mids and less glowing tubes. Today i found an old sovtek 12 ax7...

Hit a power chord on my '72 Champ, and there was a fading of the chord about a second after I hit the chord, and flashes of light from the vent holes at the bottom of the output transformer. I was sick. I have purchased a Classic Tone output transformer, but hesitate to put it in until I find...

Dear Members, This is my first post. So i'll try to keep it short and sweet. Last week i bought my Fender champ 1981. I looked up everything about it! How to check hot tubes, burns of components and all these things the little champ can surprise us with. Well, everything is fine and original...

I Picked up a Boothill 5F1 kit a couple of years ago and it sat, and sat...kids, a move, life. Over the summer I've found a bit of time here and there to finally get this kit going! I'm learning a lot about word-working as I go, mostly how much I like making stuff. I wanted to build as much...

I went to downtown Tokyo this afternoon. I picked up the Kluson Type Gotoh Locking Tuners for my Fender '86 AVRI Stratocaster which I ordered by phone in Ochanomizu. After I looked around some guitar shops, I had not much to do on this Sunday and walked to Akihabara. I thought that I looked for...
