Fabulous job :thmbsp:
How did you clean the relay contact surfaces? Ultrasonic again, or very fine grinding paper? Which grain, in that case? Or some sort of polishing compount?
.WOW!....excellent work. Excellent photos too. I dare not clean switches like you do, for fear of busting them!

You missed a spot . . . . NOT!
Amazing work. Beautiful unit. :thmbsp:

Aren't these different boards??
For the pilot lamps - scale lamps in general - I use special dipping lacquer. Green or blue - to get the original illumination.
Fantastic job! You seem to be very passionate, I've got a V5 and a V6 , hopefully a V7 soon. Congratulations on your lovely system, it's just beautiful !
