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.

My friend owns a vintage repair service.He has told me that the Counterpoints amps used a transistor that is out of production,and that he won't touch the units.I imagine someone could rework them with another device,but I'm not sure it would be economically viable.My advice:steer clear!
