Believe the "Bandwidth warning"! It took a long time to download, but
well worth it.

Your letter in the March/April 1977 issue was about (you'll never
guess) the EML 200/300! It resides there with a letter from Barry
Klein, who, I assume, is the same BK who wrote the first book on
"Electronic Music Circuits" I ever read.

I suspect you already know the "usual suspects", but here ya go:
If the noise sounds like 60 Hz hum, accuse the power supply (always
accuse the power supply first, anyway).
Did it work just before you moved it and suddenly went wrong? If so,
look for a loose connection. If the noise arrived more gradually, try
the capacitors (it's about time to re-cap a 30+ year old, jeez! I'm
almost ready for a second re-cap, myself).
Another usual (not for your instrument, but in general) process -
re-seat the ICs in their sockets. If you find ICs in your EML stuff,
time travel is possible!
