The amp is from 1976, are you looking at a schematic that old? The values used would likely have changed since then, also the caps may have been replaced since '76.
As far as the tremolo pot, maybe it just needs a cleaning?
P.S. You said it was an "import type" amp, I thought in '76 the were "made in USA" and marked as such on the rear of the chassis?
