Thank you. The drawing does not show that shield at all. I'll repair that just to be on the safe side. Next rookie question. The AGC resistor had drifted low. Spec was 9.1 Meg, the one in there measured a little over 1 Meg. I put in a new resistor that measured 9.113 Meg. It measures a little over 5 Meg in the chassis. That resistor is not paralleled with anything else that I see. Should I look for something possibly loading the AGC line? If so, where do I start? Rookie question number two....there is a choke of some kind in the plate circuit to the 6DA4 damper tube. One lead on the choke opened, killing B+ to the plate of the damper. What is the purpose of that choke and what happens if it is not there. I fixed the break. The choke measures an ohm or maybe less.
