OK, this is getting weird.
I couldn't sleep and tested C45 around 0230 and found it does leak a bit, about 12uA at 15V.
This morning I put my AVO on pin 2 of the EL84 as per Rob T's suggestion and all seemed well as the voltage started at -7 and slowly fell to -14. The odd thing was that the radio was performing much better.
I disconnected the AVO and it sounded lousy but picked up as soon as it was reconnected. I tried my digital multimeter and that had the same effect.
I'll get these caps changed as they seem iffy whatever but some sort of explanation, suitable for a bear of very little brain, would be appreciated.
Cheers
Joe
