Hello. Start with the easy things to do. I would clean all tube contacts and tube pins with Deoxit. I use thin strips of the green scouring pad (scrunge?) with the Deoxit on the tube pins. For the tube sockets try Deoxit on a Proxy brush (dental brush) to clean the contacts. Let everything dry completely before plugging it back in. You can also take a wooden chopstick and tap components on the chassis and listen for any change in the static. Minimal investment required, and at least is a place to start. Good luck! Take care and BE HEALTHY! Gary
