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.

Counterpoint amps can be completely rebuilt by Mike Elliot. Most other amps can be repaired if parts are available and in some cases modified if the same parts can't be obtained.
