Ear rape.

@mike6l6 Put some metal covers over the pre-amp tubes. It creates a ground shield and cancels out a lot of the noise.
-
The preamp tubes are too close to the output tubes. When i build amplifiers ,I always put the 1st preamp furthest from the output stage
-
Great tip!

I have eliminated the problem now by readjusting gain levels in the FX loop circuitry and switching to a lower gain tube there too, and installing real tube shields over the preamp tubes.
