McIntosh MR-74 no audio output
Looking for ideas in things to check. I’ve got the fixed output on the tuner going to my preamp but no audio is heard out. I’ve made sure to keep the muting feature off. Not getting any hiss or anything from the unit. -
Is an MR74 worth repairing?
I got a really beat up MR74 and I'm wondering if it's worth repairing. It powers up.

Looking for a cabinet

I'd like to acquire one (presumably an L12 or L52, is that right?) - looking for recommendations. I am not a stickler for an original, in fact I think I'd likely...- Jaynudel
