Hey David, go immediately to
http://www.triodeel.com and then go to their transformer page and look up Dynaco replacement transformers, perhaps the MQ-431-CL. You should be able to find an exact replacement(as you may or may not know, Sunn amps were based on Dynaco hifi amp designs). Their direct replacements should work much better than what Torres suggested. (FYI...there seems to be a bit of controversy regarding how Dan Torres fixes things--if you go to
http://www.vintageguitar.com and check the "amplifiers" bulletin board you'll find a few people not too happy with the work he's done, however, I've learned quite a bit from his book, "Inside Tube Amps", so take it all with a grain of salt). Also, take a little time to go through the triodeel site, there's alot of good stuff there, amusing links, etc. As far as that cabinet you're looking at is concerned(thanks for the direct email)that definitely would be a classic early Sunn cab(is it 11" deep or 15"?) --those speakers are probably JBL's, but I would still verify it. $399 is a little high...even with JBL's , I wouldn't pay more than maybe $275(but that's just me!) Good luck, Mike
