Re: I need help with my MA-240

Lew, you're quite correct about the Socket. The grid pin may not be making a good connection. These sockets can often be "retensioned" by carefully squeezing their spring metal parts with a needle nose plier.

The grid resistor could also be open. It was 680 ohms, if memory serves.
