Expectations after re cap of power-amp


My 1982 Yamaha M-2 power amp is in the shop and this time I agreed to replace all the suspect capacitors. Two of the capacitors are the size of coffee cans and the total bill may exceed $500. I am told that since all the replacement parts will be as good as or better than the original parts it should sound as good as new or better.

I’ve never done this before.  Should I expect “as good as new” or am I completely wasting my money?

Depends on the quality of the caps used. Could be quite a bit better than new. Talk to the tech, ask about how he selects caps. There is a huge range of performance- and yes you do pay for better.
Replaced all the electrolytics in a tube amp with 15 (hot) years on it, and it made a very nice sonic improvement - - all upside, no down, and no dramatic change in the overall voicing of the amp.  I hope you will be as pleased with your recapping.

My caps were not expensive high temp, low ESR Panasonics, FWIW.
I replaced all the caps in several vintage amps with Elna Silmic and Nichicon FG caps and the improvement was significant. For the $50-75 I invested it was well worth it. What amp could you buy for $500 that would compete power wise with the Yamaha?
