Output transistor suggestions for McIntosh MC2105

MikeBettinger · 21st September 2011, 12:34 AM

I'm resurrecting a McIntosh MC2105 and was hoping to find either specs for the original devices or a suggested replacement. The amp has been repaired a few times and has a collection of devices in one channel that looks like some dug through their junk box. I'd like to replace the outputs and drivers with more appropriate devices relative to what was available when the amp was built.

Thanks, Mike
