Looking back at the measurements for V4 (CL33): -
- Anode (Pin 3) 255V (and some scratchy noise from speaker)
- G2 Screen Grid (Pin 4) 138V
- G1 Control Grid (Pin 5) 0V (hum and scratchy noise from speaker)
- Cathode/G3 (Pin 8) 4.8V
G2 seems slightly high (should be 110V) but if these are within tolerance as are R16, R17 and R18 then can I assume that C27 and C29 are behaving themselves??
I'm still not satisfied that I've got the HT supply side sorted?
