[QuadList] Got my VR 1200's

[C. Park Seward]

Hi Doug

You'll have fun working on your "science experiment".

Air pressure 55 psi +- 2 @ 2.5 cfm.

I bought a cheap Sears and an expensive Gast. Love the Gast.

Get a ESR meter to check the caps. Around $100. I used shotgun caps  
until I discovered that the caps in the 1200 were actually better than  
new caps! At least as far as ESR.

THe big caps in the PS could be replaced but they are expensive. I  
have a PS guy who has repared sone of mine.

Best,
Park
