If no joy then short the control grids of V5 to chassis, that's pin 3 and 4 of the 6SC7 to chassis and note any difference.

I did tie the pin 3 and 4 together to chassis. Unfortunately no sound is coming through the speaker or no sound on the external speaker plug either.
Hum is reduced and no any other issues but the sound has gone...
