thanks again bill. both grounding points (PS PCB and IEC socket) are bare metal, powder coat and primer have been scraped away. new rca jacks should arrive any minute now with the rest of my PE order.I just discovered something else, though. The center pin of the bias jack for tube socket 'A' has a resistance of 10 ohms (to ground), as it should. The grounding tab, however, shows continuity to ground, which it shouldn't. Nothing that I can see is shorting it out. My only thought is that some paint has been scraped away accidentally and it's grounding directly to the chassis. Is this a problem?
As an aside, I get an open loop when probing the from a ground wire to chassis through the powder coat - maybe the paint is just thicker on my amp?
