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?

The responses have all been very encouraging, thank you so very much.  My worst fear would be that the amp would sound worse not better and I might waste the money invested and butcher what was once a well respected amplifier.

 

I don’t want to throw good money away but after the responses I received I don’t think that would be the case.

 I was shopping some expensive (and powerful) power amps and everything I looked at was $5k - $7k. So if I can get my old Yamaha back to ship shape for anything like $500 I am all in.

I will repeat myself because I think sincere gratitude needs to be expressed. All the generous feedback has been very encouraging and because of it I now feel far more confident in my project. All these responses are not a trivial blessing in my case.


If recapping is a fool’s errand why bother? Better to use the money toward newer amps. I needed to know. I may do both but I would like to express that the Yamaha M-2 was well respected back in the day. It is still possible that I may yet invest in some Classe gear after recapping the Yamaha.

I have some Dahlquist DQ10 speakers I spent $2,000 on rebuilding them before I retired them.  I still own them. Even though I seldom use them I’ll argue that I owed them something for their decades of faithful service.

Ever own an old faithful dog? Nothing was too good for my Christopher.
