repairability of amps from the late 80's and 90's


Hello,

Is it true that certain amps like Counterpoints, Fortes, and some other are difficult if not impossible to repair if their output devices should go bad. It is my understanding that they used IGBT (?) or particular MOSFET devices that are no longer made. Thanks.

Thanks everyone who has brought some clarity to me regarding this issue. It is good there are still resources out there to take care some of these amps. With the Counterpoints, it sounds like it may lead to an expensive path.
Rgodin,
