How can I repair bubbles in front glass plate of MR-74 tuner? Are there two pieces of glass glued together - cannot tell without trying to separate two pieces. If the glass pieces can be separated, what paint should I use to touch-up bubble spots?

Thanks in advance for a reply,

I am in dire need of upgrading my current system. I want to return to a separate preamp and power amp. Are the 30 to 40 year old McIntosh units worth the kind of money the current market demands. I have been an admirer of Mac Equipment since my audiophile beginnings in the early 70's, but as a teenager, I couldn't afford it. I am considering a MC2105 power amp at the moment to start with and will also need a preamp,too. I've seen these on various websites ranging anywhere from $800 to $1400 with various conditions of the units claimed by the sellers. Is it worth spending this kind of money on a 40 year old pwer amp ?

I ran across a Dyna PAS at a garage sale. It was in working condition but sounded very bad and the tone controls were damaged. I sent it to Cornell---%3E what I got back was astonishing! This unit now performs even better than the one I had about 40 years ago. It sounds stunning and everything works perfectly.

I just sent you an e-mail. I was thrilled to fine this website and you in Phoenix. I know Frank McIntosh lived on Camelback Mountain in the 80's. My backround included high end retail sales in Menlo Park Ca. and as a McIntosh Manfufacture's Rep in Northern California in the 60's.

There are quite a few MC preamps out there that should work fine. Check with Audio Video Choices in Phoenix, they may very well have something in stock that will work. www.audiovideochoices.com
