The film caps will actually 'sit' on the bottom plate (the one with the ventilation slits).
There will be a piece of sorbothane between the bottom of the caps and the plate. Vibration control?
Twist ties, and more twist ties.
But let's think about this. The MA-1 is arguably one of the best amplifiers on the planet. I have installed IXYS full wave bridge rectifiers, oversized capacity. There are two Mundorf HC+ low voltage storage supply caps, 4-pole version. I've ordered CuTF 0.22uf coupling caps. The Mundorf film caps obviously. Some of the resistors will be upgraded to Kiwame. There may be other tiny changes.

Why, my friend, would I ever sell the greatest amps on the planet?

You would do me a great service if you'd just answer some of my questions. If you know the answers of course (I'm gonna pay for that one).
