Voltage between grid and cathode = -2volts.
Across R9, R11 = 24v.
Across R10 = 2v.
I think as you have indicated that the readings are correct and the amp is functioning correctly.
Thank you for your help.
Nick I haven’t removed V2,3, not sure if this will achieve any thing, considering what Lawrence and Graham has said, and the voltage reading I’ve indicated.
Any further thoughts, or can I put this to bed?
Cheers
John
