[QUOTE="Family_Dog, post: 1026067, member: 82"] Replace the coupling caps, don't even worry about testing them. Replace any other grey Suzuki cap as well, they all leak. Note that the 6BM8 output valves share a single cathode resistor and Cap, bad move on Pioneer's penny-pinching side. Note too the cathode voltage at 173v which is completely incorrect. Other than that, it is a nice little amp! -F_D [/QUOTE]
