I powered up a Johnson Ranger 1 over the weekend. It had not been powered since 1973 according to the previous owner. I brought it up slowly over a 5 minute period using a variac so as not to just slam HV on the original electrolytics. It powered up fine. 6146 was dead so I replaced it and was getting full power output. I did notice the oscillator is moving around some. The transmitter signal sounds good and clean on the receiver, just the frequency is moving a little bit here and there.
I would like to peruse the VFO compartment but it looks nearly impossible to get into without major disassembly. I'm trying to remember back in the mid 90's I accessed my Valiant VFO compartment from the left side, to replace the 6AU6, OA2, and burnt series current limit resistor. Even then access was limited from the side, cramped space, difficult.
I see the side screws that affix the lid go all the way around the top edge, including two screws facing the VFO dial. Can't get at them. Has anyone here gotten good access to the VFO compartment other than coming in on the side? I fear the answer is something like total vfo disassembly...
