what will be the best old CLASSIC amp to rebuild.

Personally, I would find a person who is qualified to rebuild an amplifier and discuss it with them. No sense buying some old non-working amp and not being able to find someone to rebuild it. Unless you have someone local, I think it's not a very good idea anyway. Look what happened the last time - some guy rebuilt an amp for you and it came back with a hum. Now you have to ship some 100 pound amp back? My advice - absent a local tech, forget the idea and just buy something new that you can live with. If you're really that picky about sound, get your wallet out and forget about $1200.

"Do you think a rebuild classic power amp will offer better
money return than a modern power amp??? $1200 is just a
budget reference as i know some power amp are very expensive. Hope it more clear..."

I think it would be best to just get a current production amp. There's no way you can audition a classic amp before you have it rebuilt, so you will always be taking a chance. With a new amp, you can listen to it first. I think you can definitely make a better choice that way.

If you live in France, you probably know YBA. A few years ago, I heard an integrated amp from them and thought it sounded great. I remember that it wasn't too expensive. I'm guessing you can get one used for around $1200. I don't remember the model; maybe it was 201, but I forget. It was black and looked similar to a Wadia CD player.

thank you for your advise, i never considere the risk of
buying an old power amp and expect a great sound from
something i have never ear.Modern amp has the chance to be demo before buying same used.This advise is very wise.

I found a Emotiva XPA-3 power amp i will audition this week end.Some good review about this model.

I understand now that rebuild a power amp it when you have
a unit you love and want to keep and giving a new life to
your lovely old power amp. Audio is a mistery where advice
from other more experimented help us to achieve our dream
of enjoy the music...

I'm from Québec where the majority speak french.

I also agree that budget is not a concern when you want
the best of best. I have two Gibson SG 1970's one with
p-90 and other the luxe with PÄF and stereo output very
very rare. I just saw an other one SG like mine in stereo.

Nothing can compare a vintage instrument regarding the
sound quality same a custom shop at $3000 will not be able
to emulate a old wood vintage sound. In high end audio it
the same very high quality equipment can't be emulate you
have to paid for.And we paid for because we love music.

Thank again to share your experience.
