Last night I fell asleep while listening to music for maybe an hour and immediately turned off the amp and preamp. I couldn't fall back to sleep so I decided to turn the system back on and heard hissing and rumbling through the right channel. Figured a tube went bad so I turned everything off. Found a post about noise on this forum that suggested cleaning the tube sockets. I figured wiggling the tubes around might help and sure enough it did. I listened to another CD and shut the system down.
Is there anything else I should do as a follow up?
