Re: TL-922 tube filament voltage.


 

Yeah Mikey, I concur.? I used to install copiers (50 years ago) and I had to install buck/boost transformers in certain parts of Grand Rapids MI because the infrastructure was old and the voltages were either high or low, mostly low.? On one location, I found that I was working with 89 VAC at the wall.? The copier just wasn't about to work right.? It took TWO boost transformers to get it to work.? I was complaining to Consumers power here about low voltage here.? I've got two AC units and a 6 KW booster water heater for the dog grooming shop here that my wife runs.? When everything was running my line voltage was sagging to about 106 VAC.? Light load it would come back to 115 VAC.? So they did some maintenance.? I now have 125.5 to 126 VAC per leg.? Under full load during the summer it will drop to 123 per leg.? But I don't have the big? sag and AC compressors that won't start anymore.? My air compressor isn't blowing starting fuses either.
?
I will say that I HAD to prove to Consumers that I was having an issue.? Pictures of the Fluke stuck in the wall was the trick.
?
Just came back in from the radio shop and did my daily check of the wall voltage.? 124.8 VAC
