I have one completely pulled from the amp and it test the same---zero. As I said, I did pull one side of each remaining resistor ckt and it tested like the one i pulled from the ckt in its entirily. With two of these resitors in the ckt the A side appears to work(tube lit etc , except for the heat sink transistor( they are really hot). If I should be getting a reading on these( like i think i should) and I do not then i am in a world of deep electrons
