Factory service for products from the 90's

I just ran into problems that certainly apply here. I have a McIntosh MC7200 amp from the early 90's,making it around 30 yrs ago. No problems with it at all. However, I went to change the lighting bulbs for the second time, only to discover that due to the heat of the lamps, the plastic housings around the meters, as well as the light socket holders are all disintegrating! I called Mac's parts and service. I was told there are no replacements for the housings, too bad on the socket holders, the circuit board that the light bases are soldered to are no longer available, and the actual meters themselves are no longer available. I also contacted Audio Classics and was told the same thing. 

So it makes me wonder about all this, and the fact that in the future I could have a Mac amp that would look awful, meters that don't work, lighting that no longer works, and what else? Maybe some of these meterless amps you see ( i.e. Parasound, etc) aren't a bad way to go. I love this amp, meets my needs perfectly, but I'm a bit frustrated and this looked like a good place to vent!!

@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.
