Factory service for products from the 90's

@sid42     I have a MC7300 which I have owned since new. Last year I sent it off to BobTheTechAudio.com for servicing for some minor issues and to have the bulbs replaced. I’m not sure he can help you but he is very knowledgeable and is great to correspond with. He kept me abreast of everything he did and recommended. He could advise you further.

laps, thanks for the info. I'll see what Bob can do, if anything.

Krell services their amps of 30 years ago. I don't think you could buy a new amp anywhere near the quality for what the repair would cost.

My experience indicates very significant positive progress in fidelity is made by the time ten years has passed. So, of course, old equipment is much cheaper, and repair can be inexpensive. An older amp should be cheap. Whether this appeals to you depends on what you are going for and your budget.
