Hello all New member. New to the hobby. I literally found a 1961Motorola stereo console with record player and radio in pristine condition at the local dump. Took it home, plugged it in and worked like a champ. Unfortunately, after warning my wife not to leave it on because of over heating,you guessed it, she left it on and it overheated and no longer works. Where do I go from here? The amp is a HS-839A. I tested all the tubes in the stereo and they checked out. I bought a second HS-839A online but to no avail so I suspect it has something to do with the pre-amp, but what the heck do I know? Your advice is greatly appreciated.
