I am an audiophile that has been sitting on two mint McIntosh car amps (I'd never sell my McIntosh tubes) in the boxes with papers that I purchased new:

MC443M (100x4) and MC431M (500x1) are the model numbers.

I also have a brand new Butler tube amp TD750 (2x75) that I'm not going to use.

I'm going to put these on ebay sometime this week, but figured I'd give any interested MB enthusiast first dibs.

I just have too many projects and not enough time.
