|
Between feedthroughs F (magnet coil) and B (tube heater negative), I found a jumper with two resistors that has been burned up. I am not sure when this
happened, but it would be good to review the overall setup of the service cap wiring in the new year.
The cable connected to feedthrough Q where the multipin sits also looks burned. |
