I've acquired a PCW9512 which works (or at least shows the expected white screen with no disk inserted - disks are on order). In the process of removing the cover it became obvious that someone has previously broken the contrast and brightness knobs so when I went to pull the plastic covers off they went all floppy.
Opening it up fully, both variable resistors are broken but had been hot glued into place. Hmmm. I don't have a problem replacing them but not sure what values they should be. The service manual helpfully gives values for all of the variable resistors on the board, except these two. It describes them as a 'gang' but doesn't give the actual value of either.
On top of the first one is the number '104' and the other has '501'. So, could that mean 100k ohm and 500 ohm? Or am I barking up the wrong tree?
