[R-390] R390A trimmers

[Graham Baxter]

Hi All

Does anyone know where I can buy some of the ceramic trimmers as used
in the MHz bandswitch crystal box? There are three different values
and I need a few of each, 12, 25 and 50 pF

Has anyone else noticed that cigarette smoke condensate appears to
attack the rubber washers which are part of these trimmers? Then the
bottom ceramic plate breaks loose.

By the way, I am still looking for an audio output transformer,
preferably from an EAC but beggars can't be choosers. PayPal waiting!

Thank you

Graham
