Gentlemen, let's be kind to one another. Sure all the wax and lyticic caps need to be replaced, but trouble after 10 minutes playing very often points to a carbon resistor drifting over the rainbow. Tube troubles usually show up sooner than that, but not each and every time. Bad silver micas usually crap out much sooner than 10 minutes. Ping around gently with a dry chopstick to rule out mechanicals as in tube sockets. Lots of other ways to locate point of failure, but why not start here.
