Normal or abnormal ?
Came in for an intermittant problem, fixed, and the following the owner
lives with but is it normal or abnormal?
With feed into a "normal" input and the "brilliant volume" at zero then
there is no control of the bass on the tone control, you need to have a
little advance on the brilliant volume.
Trouble around V7 ECC83 ?
DC voltages cathode,grid,anode
"brilliant half" 0,1.4V, 182V
"tone half" 182,183,290V
all associated pots ,Rs and Cs check out agreeing with schematic as does the
valve and same Vs with a different valve
