I did order a replacement quad cap and will replace it in the fall. too hot here now in Vegas to use any tube equipment.
I did the "rca jack" grounding upgrade and that helped to reduce the hum.
Also I resoldered the ground shield that covers the variable tuning capacitor and regreased the bearings with that dern expensive silver bearing conductive grease.
Oh and I replace the somewhat corroded front panel screws and that must have helped the grounding also because tuning is much less noisy.
The FM-3 sounds better than my modded Sonys that's for sure although the sonys sound very good. The FM-3 is just in another league...
The hum is gone now even though I have not yet replaced the quad cap, but I will do so eventually...
