Frank,
If you drop me a private message I will gladly drop a couple out for
you and measure them. The ones that hold the KLM-367 down are the
same as the ones used for the other boards attached to the wooden
chassis. So providing they are all not lost you should be able to
find at least one example. The others are metric metal screws, but
I'll have to measure them!
If isopropyl doesn't work for me then I use a product called 'Mykal
De-Solv-It'. You can get this in the UK and Eire from Radio Spares
(RS). I have found that sometime the laquer from the green parts of
the board gets onto the gold contacts. A vigourous rub with Mykal and
you will have a very clean set of contacts indeed. Also please ensure
the black switch contacts on the rubber parts are mat black with
no 'mirror' image on them. I can send you photographic examples if
you wish.
Cheers,
Andy
