it sounds like to me it's either a bad solder joint, loose connection,
or just a failing tube. the fact banging it fixes it indicates to me something is loose. with close to a thousand solder joints in that thing, have fun. i'd start out with the obvious things..check pins on connectors, cable connections...anything that looks like it'd get some vibration. |
