Hi Radek,
If D3 is permanently lit then data bus component DO3 with be stuck low.
Check the connectivity of IC22 pin 15 to IC31 pin 2, IC31 pin 3 out to
every connection where the data bus fans out.
I do recall the other problem and it is caused by cross talk on the line
that carries the VCA signal. A quick search through the forum should find
the article! I think you have to cut a track on the effects board, but I
could be wrong.
Cheers,
Andy
