Electrolytic Capacitors on the the various power rails
are likely components to fail.
Also diodes in the power regulation, but that's more obvious
to find.

If the encoder's dodgy,
then it won't take you through all the presets (1-16).
That's a common fault, and Lexicon don't have any encoders left.

Luckily Bob "Jamman" Sellon is on the case.

Cleaning is possible, but not a long term solution.
