Long-Term Amp Storage Without Use: Bad Idea???

But they are kind of rare and all tricked out!

Well, that's just what you want to keep in storage. :)


Seriously though, simplify and minimize and it will help you focus on your goals.

I would just store them.  When you do plan to use them, it would be best to slowly bring them back to life using a variac (this allows the capacitors to slowly "reform").  If you hear noise, particularly hum, after the amps are up and running, it is most likely some power supply electrolytic capacitors have dried out and need replacement; any competent technician can do that, and if the amps are valuable, that would be a small price to pay.

I suppose "long-term" i s not really a precise term, but, I've heard many amps that were not used for more than 30 years that work perfectly today, even without capacitor changes.  A friend recently bought an amp that is probably 65 years old that is in perfect working order and sounds great; it has all original parts, but I don't think that he knows how long it had been stored before he bought it (I would guess quite a bit of time because the tubes are ancient).

Listen to the dude Eric as he knows everything about everything WOW!!!

There's a really good chance that 10 years from now there will be better amps and better parts with which to trick them out.
If you really plan to not use it that long, just sell it and buy a functioning amp 10 years from now. 10 years is a very long time for filter capacitors to sit without a charge! You'd be better off keeping it in service.
