Found an Ampeg v4 needing a transformer very cheap..
 

How much (ROUGH ballpark) could I maybe spend on the transformer (if in fact it is just the transformer) ? And are the possible to source easily enough?

It needs tubes also but that is a much easier to find commodity..

Ok I just found one quickly doing a internet search ($200.00) soo.. any pit falls with trying to bring fourth this Phoenix?? Are schematics available? (Im going to google again, lol)

How much is the v4? I Imagine a tech could replace it easily if you didn't want to do it yourself.

About $150.00 and transformer is about $200.00 (that is of course if that IS the only issue)..

Also look @ fliptops.net

YES, that is where I found it..

Might also need a cap job. That could run about $200 if you pay someone to do it. But still worth it if you like the amp.

Schematics are available at http://www.ampegv4.com/

The fliptiops product is a good one, made by Heyboer. You asked about a transformer, there is the power transformer and the output transformer. Order the correct one. Unless the transformer is missing, be sure that you really need a new one.

If you can get the amp cheap, it's worth it to just drop it off with a tech and have them order what is needed. A cap job on a V4 should be about $100-150, I think I paid like $120ish when I had mine done. But the tech can do all the repairs and clean up and be sure it needs a transformer before you go ordering one.

Transformer failures on V4's are pretty rare.

What tubes did these use on the power side, 6l6gc's?

Usually 7027A's but 6L6gc's will work so long as they are good quality. Also KT66 and 5881's
