[sdiy] Model D service

[Magnus Danielson]

Among modifications implemented is changing VCO board.

Depending on VCO board, one problem is that TEMPCO resistors does not 
sit on the expo-pair transistors, leading to poor temperature 
compensation leading to instability in frequency which is something you 
may or may not want to fix. I know of at least three different VCO board 
versions.

The service manual and its trimmings should be followed naturally.

Cheers,
Magnus
