Hello,
Seems like this thread might be better located in the electronic restoration bucket, but I have no idea how to move it there. I did not post a video of the remote control pulsing output. It still has the original paper capacitor. Since that capacitor is sitting directly across the 45 volt battery, if it has any leakage at all, it will slowly deplete that battery, so it will be replaced even though it appears to be working fine.
I do have one wire that was disconnected from the channel lights (or at least I think that's where it was, as it looks to be supplying the common 6 volts for the lights). I was trying to figure out where it should be connected. In checking the schematic, I ran into what I think is the safety capacitor connected to the primary of the power transformer before the on/off switch. The parts list shows it as a Bypass condenser .05 mfd. Since that capacitor is connected from line to neutral, I'm thinking I should replace it with a Class X safety capacitor. Is that correct?
I'm sure to have lots more questions. I do have 5 tubes that test dead. Two of them are the 42 output tubes. I'm hoping it's just the filaments and not the output transformer. So, I will be checking that transformer to make sure the windings are correct. One of the other tubes testing bad is the 80 rectifier, so there will be some checking of the power transformer windings. I will not be testing the chassis with my Adjust-A-Volt unit until I replace the electrolytics and paper/wax capacitors, and all of the deteriorated rubber insulated wires. Does anyone know if the 42 and 80 tubes are still available, or are they unobtainium?
Thanks,
Rich
