Hi
Leon1210 again - I see you have coated the inside of the main deckplate with some kind of compound - why? and what is it? I am very curious.

Best regards - Leon

Hi Russ,

I'd like to give this mod a shot. Haven't picked up a soldering iron since 1976, but what the hell. Where did you mount resistors R1 and R2 for the voltage divider?


Best,

Mike
