Scott, after a 3 hour conversation with Ed last night, it was realized that Cathy may be double Zoebeled. In early, early Ser I's the zoebel was mounted on the meter board. Check and see when Cathy gets there if there are 2 5 watt 10 ohm resistors and a .1uf cap on it. I think there is and it has not ben bypassed. No harm will come to it but can sound funky at times./ If you desolder and remove the Zoebel it should still drive the meters with no jumpers installed.
