Additional comments and another choice for your TL922 3-500Z filaments. I just downloaded and examined the TL-922 amplifier service manual. I traced the input power circuit and the TL922 doesn’t

At 252 I might be concerned about a bunch of things in your house. Sent from the all new AOL app for iOS

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

Not to belabor the point but it is wise to monitor you incoming voltage and note that at times it will change. I have quite a bit of classic equipment that was designed to run at 115~117VAC. I

Thanks for the info Dale. Upgrading the service to the house DID make a difference.? I went from 238 to 252.? It had to do with the replacement transformer and service conductors. BTW, I use a Fluke

Ohmite offers bolt down fractional value resistors in metal casings of 10 and 25 Watt values. For a single 3-500Z dropping 0.5 Volt at 15.5 Amp requires an 0.17 Ohm resistor and will dissipate 7.25

Lou, Good point on the meter. In the past if you talk to any electrical company about voltage they'll ask you "what meter are you using"? Bob W4JFA [email protected]> wrote:

Updating a service really doesn’t raise the actual voltage coming into your house. ?The only thing upgrading does is increase the potential current available to you. ?With no load on your service

Hi All, I've appreciated all the info that I've gotten on the Kenwood TL-922A and I've ordered the relay switching board from Harbach.? While I'm in there, I'd like to address the filament voltage.?

FYI: " WARNING: *Never mix ammonia with bleach*. This causes the release of toxic chlorine gas, which can be deadly." Read ingredients of the products you are mixing.? If they have the above in any

It’s not worth the effort to eliminate the nicotine covering on any radio, despite the radio’s value. Your life is worth more. If you can return it if bought, do so. If not trash it. I’ve done

Good safety info reminders, thank you. Meanwhile here is #2 bread slicer, before and after. Soon as it was immersed, there was a tar film that appeared in the surface near the bubbles, it almost

I know of MEK, its very brutal...a rag with some on it will strip paint immediately off metal with only one wipe. I dont think its wise to be using that in our trade, way too powerful. -- Steve Hearns

"Scrubbing Bubbles" will remove nicotine from metal and paint. Don W4DNR

In a recent Shure fatboy rebuild from 1941 and 1943 the re-plating of the zinc frames were called for, but it was up to me first to get rid of years of nicotine build-up from chain-smoking radio

That type of thing happens when you inadvertently mix an ammonia based cleaner with a chlorine based cleaner.You get the same kind of gas that was used on? troops during WW 1.? Ain't good.? Even

This is an important caution below from Kim. I did mix cleaners together for a difficult cleaning. It hurt my lungs and put me in bed for a day. I did recover. I realized I was being poisoned before

Just a caution here.? Be VERY careful about what you mix together.? It's very easy to poison yourself from a BAD reaction of the chemicals.? Just a heads up for others.? Personally I've always

Latest photo of the chassis as I am removing and cleaning each individual assembly. Just took the top bread slicer out and I have a seperate plastic container I will fill with the Fan-monia and let it
