OK, here's the stupid question:  What is a mfd disc (microferrad?) and what
will this do?
I'm willing to try anything to get the VSS controlled functions working
(doesn't have to be particularly accurate) but my specific knowledge of
electronics is limited to Ohms law I'm afraid! :)
Could you give the dummy explanation please?
Thanks for your help,
