I picked up a '83 Super Champ the other day, it's in almost mint condition. It still has the original tubes and after testing them on my Tube Tester they are still in very good condition. They look like they have never been pulled until now. Guy told me he bought it new and only used it on occasion. He didn't have the footpedal anymore.

So my first question: Where can I find a pedal for it?

As a self appointed tech of over 30 years, working on 100's of amps (as a hobby not a job). I opened up the amp and took a look inside. I knew it was point-to-point wired but I also discovered it had lots of Orange Sprague caps in it. No wonder it sounded so good!

Second question:

Did they make them with Sprague caps?, it doesn't look like it had ever been opened up and I couldn't see any signs of re-soldering, very clean through out.

Final question: Tube V3 is a 6C10, why did they choose to use one of these? Save space, function, or some other reason? No problem I have a few and some subs if I need them. Other than a few Ampeg amps I've never see them used in guitar amps. Interesting, point for discussion.

This baby is a keeper fore sure.


Now That I know how to post photos here's a few of the amp.......



Thanks for any info on these amps.[imgImage]

The 6C10 is a triple triode and was chosen for space-saving reasons. The SC's had cascaded gain stages requiring more bottles than the chassis could physically accommodate. Thus, a tube with three distinct sets of independent elements offered an attractive-and-logical solution.

The Super Twins, Super Twin Reverbs, and the Studio Bass amps used similar architecture and employed the 6C10 for the same reason. If you have a stock of NOS 6C10's, guard them like your daughter's virtue -- they're worth their weight in gold.

I was looking for a footswitch for my 1970 Princeton and Fender Consumer Relations directed me to Music Parts Guru. They had what I needed. I would buy from them again.

I hate to say it but $35 for a tube plus shipping is a rip off. :P I've seen NOS 6C10's for under $10. I think I have enough to last me 2 or 3 lifetimes, maybe I'll sell them when they reach $100 a tube. :lol:

They have gone up quite a bit since the Rivera era Fenders have become more popular.

Tube tester can't show you if tubes in amp are good. Amps tubes need high voltage and proper load to work that thing tubes tester can't provide.

Tube tester show you only that the tube is not dead, or short but not if it working properly

That's totally wrong! Who told you that, crap?

Growing up in a TV repair shop in the 60's, My Dad's Shop. I did lots of testing of tubes for him and learned a few things along the way. His first Rule was to "Never put a tube in anything until it's tested". That Rule still works today. Have you ever tested tubes? I've tested thousands of them. A tester will give you the lots of information about the condition of the tube such as, Strength of the tube by measuring the resistance on the Plates/Cathode it will also check for Shorts, Grid Emission, and some Testers can do a Life Test (Gas Check). Tell me none of those test are important. You don't need to test them at 400+ volts to know if a tube is good or bad tube. Performance testing is anotheer thing, you can do it some testers, but testing at high voltage just shortens the life of the tube. If it passes the standard test I do, then it's a pretty good bet the tube is in good condition.

Thanks for your post but you need to spend a little time in the workshop before you try telling people such foolish information.

I learn electronics at school and I work on electronics since 35 years and I repair and built tubes amps.

Sorry but what I said is true.

JZ, you seem like a pretty bright fellow with some good ideas. But Stratele's opinions are respected by many on this forum (including myself).

Let's leave the weenie-wagging contests to the zit-poppers and the knuckle-draggers while we focus on what's really important -- namely Fender amps and the pursuit of tone.

I'm not a real Amp Tech and don't play one on the internet....

I'm not trying to start a fight, I guess we just don't feel the same about some things. Point is, I use all my tools and knowledge to my advantage, I don't use guess work to solve problems unless everything else fails. My knowledge of electronics is limited, but I have done it all my life.

So if I offended him or someone else I apologize.

You're a good man, JZ.

And formally trained in electronics or not, I find your opinions well-reasoned and well-articulated.

Rawk on!

Yep, I agree with Arjay ! Everybody packs their own toolbox, and that's cool. BTW How does that Super Champ sound ? Always wondered about those amps. Didn't they come with EV speakers ? Art

The speaker is a Blue Label, I think a Jensen. An EV would be nice but, I don't plan to swap speakers at this time. I've always liked the Blue Labels. And, I like to keep things as stock as possible.

As a Jazz musician it sounds great for a small amp, could be a tad cleaner at higher volume, much above 4 it starts to break up using my Guild X170. I may sub the 12AX7 for a 12AT7 and see if that cleans things up, or maybe find a good low gain sub for the phase inverter, maybe something like a 6K11 or 6D10? don't know about that possibility yet. Don't really care about the Lead Channel for jazz, it sounds good for Blues, great sustain, nice reverb. I really haven't had much time to play with it. I'll take it to the next Blues Jam just to try it out with a Strat.
