Well here's where I'm at so far: Replace power supply quad cap with four individual 33uf electrolytics, Replace the two 10k 2watt resistors with 3watt units, replace MPX section capacitors C29 and C31 with orange drops of original value, replace two .10uf coupling capacitors with .47 Russian K40Y PIO, and replace the 6AT8A tube with a NOS sylvania. It's just a little bit on the dark side right now, the PIO coupling caps might be a little much when combined with the inherant factory treble roll-off of the FM-3. Think I'll run it for awhile to let things settle/break-in, then attempt an alignment.
