Finally got around to getting myself a Super Champ – 1983 Rivera era. I've wanted one for a long time Why do I love this little amp? It's the originality of this basic but multi-talented little amp that facinates me. It has features that are not to be seen anywhere else, certainly not in this combination. I believe it holds a special place for Paul Rivera. Mine is in original condition, with only some of the tubes replaced, will I leave it that way, and respect its humble crudity and forgive its inherent faults, love it for what it is, preserve its integratie, whilst still plauding its virtues? No ! Here is a rough cut gem, waiting for polishing. The research and development designers at the Fender factory, having to keep the penny pinching accountants "upstairs" happy. Also, this amp had to take it's place in the family row. It has more features than the Champ II & Bassman 20, is sort of on par with the Princeton Reverb II, but less than the Deluxe Reverb II, Concert II and Twin Reverb II. In many ways the family would have seemed complete without its existance, but none the less, Rivera placed this little amp in the range. Here we have lots of latent potential that awaits realization. Such a simple circuit, point to point wireing, more than adequate power transformer, and the basic layout, parts and design concept don't need toching. But I'm dambed if i'm going to settle for – " Lousy, thin sounding speaker","Forget the footswitch, it doesn't work", "Lead is ice-picky and buzzy", "Obsolete 6C10 tube" and all the other complaning comments one hears about this amp.Identify a problem, find its cause, think of a solution, correct the situation, move on up to the next stage. First step, replace the speaker. All sorts of speakers are recommended for this amp. The original upgrade of this amp, the Super Champ Deluxe, with its oak cab, came with a EV10 of some sort, in many photos it is clear from the vaned plate on the back that it is a "Force 10", some seem to have the flat magnet that would be a "EV10M" Paul Rivera recommends ]https://www.youtube.com/watch?feature=player_detailpage&v=HC25NwrRNvo[/URL] the illusive "EV10L", which many seem to doubt the existance of. He uses in them in his special limited edition "Venus 3", which is sort of the next generation of Super Champ. I sure wish I had a schematic of a "Venus 3", I have the 5, but that's a different thing. Anyway, I found myself a speaker like the one Paul Rivera recomends and the fact is, IT DOES NOT FIT ! I've read of people bending and moving the reverb tank, but you can't take it off the top, and sawing 1/2" of the bottom, and fining some new way of mounting it is crazy. Besides the amp itself no longer fits, even with the tube cover removed, there is no room, one would have to move the tube over to the side, and the reverb transformer would still be touching the speaker. Have a look at the photos. Another thing which is undesirable, look how much of the speaker is covered by the baffle frame and Fender logo. There is only one solution, I need to make a bigger cab. Okay, I'll get back to you when I've got that done, and then I'll set to work on the footswitch problem.
