I've been visiting the forums for some time now, just got around to creating an account. Hoping I have posted this in the correct area. I recently picked up this stereo/turntable at a sale. I've been searching and cannot seem to find any information on this. I have plenty of luck finding the Sylvania Exp 4/40, not the 4/45w. I've attached a Does anyone have any information on this or can you point me in the right direction? It sounds great, then sounds like it has a bad ground, loses volume, then volume will return. So any help on this would be appreciated. Thanks in advance.
