Pilot tv crt

[timmy]

Well this pilot has issues first no sound but the original field coil speaker was replaced with a permanent magnet speaker that was hooked up and must have worked the voice coil was disconnected and those connections went to the new speaker via the field coil but just have a very low hum. The crt lights but I cannot get a hv reading maybe the probe area for the ground is not ground but rather some place else I don't know. 1b3 tests good it's new but I need to know where to put the ground from the hv probe so I can adjust the feedback ring to set the hv but the ring up or down I get nothing but there is hv. All the rest of the tubes test as new. First turn on it has a pic and after warm up the screen is unstable in different ways maybe that cause along with the hv could be the caps that were put in were ceramic disc where it don't call for those types but nevertheless the set must have worked and this whole set was recapped and they look new and the job that was done was extremely neat and clean better then factory. So if anyone knows these pilot 37 sets I would be open to a few hints, thanks.
