Tube socket for 3CX1500A7 tube-socket broken
Sorry to be a pest guys!! I've become the proud owner of a Dentron DTR-2000L amp with a broken tube socket and a missing cooling fan. This came from an estate and I'm sure that the SK was not using

Re: TL-922 tube filament voltage.
Hi, T he measured AC voltage of the 3-500Z tubes in the TL-922A as measured at the tube pins was a bit high in my amplifier, about 5.4 volts. Adding a CL-80 current limiter in series with each of the

Re: TL-922 tube filament voltage.
That sounds like its a bit high until you figure that lots of our gear was designed around 117 volts nominal +/- 10 percent.? At + 10 percent 129 VAC COULD be considered within spec.? My voltage

Lou, That's pretty lucky. I should check mine. The transformer for my house is on the pole at the street in front of my house ,about 100 feet away from the house. Bob W4JFA [email protected]> wrote:

Re: TL-922 tube filament voltage.
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

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

Re: TL-922 tube filament voltage.
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

Re: TL-922 tube filament voltage.
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

Re: TL-922 tube filament voltage.
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:

TL-922 tube filament voltage.
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.?

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
