RE: As I always advise in situations such as this,...

This weekend I have been dealing with almost the same problem on my humble diy M60. I measured the voltages on the sockets of all tubes (tubes taken out). Everything was fine except the grid voltage on V4 (-285). I suspected there is a fault in 5K trim pot, replaced it, and the problem disappeared.
