I picked up a non working Gamma V a few days ago. Opened it and noticed signs of heat and bad caps in the power supply section. Replaced all EC’s on this board as well as all caps on the IF and MPX sections. Now the tuner makes music and sounds wonderful - most of the time. Periodically the right channel disappears. I notice that the slightest touch by hand to the pcb brings back the channel. I thought the variable control was the culprit but after I removed that from the circuit still the same issue. I can make it happen by wiggling wires on the main board or putting slight pressure by hand on the board. I have thoroughly checked for solder, cracks, etc. All looks fine. Almost feels like grounding issue? Alignment issue? The tuner sounds really nice and I would like to make it a more dependable listen. Any comments would be appreciated. Thanks.
