Hi Arran,

Thanks - that would be helpful. The tone circuit is switched only, and operates in conjunction with a tapped 2 M Ohm volume pot.

The service details I found have a top-side diagram and a schematic but no wiring diagram. I traced the pot and switch wiring, and put 2+2 together about the clipped wire ends found in that area which would account for the missing caps. The laborious part was figuring out which switch tag corresponded to the numbers on the schematic - espesicially when position #6 is shown not connected, but has a wire and a cap. It's a trick - it is a dummy tag used as a tie point!

I think it all makes sense, but additional info would be very welcome please

Cheers

Ed
