[sdiy] Improvement to a Viscount cathedral organ

[Gil W.]

I opened up the PS unit today and found a corroded
disconnected fuse. Replacing it has made the hum/bzzz
noise minimal.

I also found two trimpots on the main amp circuit
which control the total and reverb volume. What is
still interesting is that the swell pedal doesn't make
much change in level between its minimum and maximum
positions...
