The amp distort at low volume, with both channels.
Tested bias: -51V. Changed inverter and power tubes at first, then substituted one at time all other tubes. Distortion remains.
Voltage DC off tube rectifier 500V on standby, 466V in "play" mode.
Other voltages: x 417V, y 455V, z 468V, power tube plates 466V.
Thanks.
