I guess that I should add that this OT was for a pair of 6V6s in cathode bias, with a 5Y3 rectifier.Īssuming the secondary is a single tapped winding, not multiple windings, you could use an ohmmeter to measure incremental increases in the DC resistance, You will need a good meter, preferably digital, and one that uses a constant current source like the better HP's or Keithley's. Any help would be greatly appreciated !!! I know they are: 4, 8, 16 ohm, and I believe 250 ohm and 70 volt? I know which is the common.the only black lead, but how do I deceipher the others? Physically, the 4 ohm would be the first off the bobbin no ? Then 8 and 16 ohm respectively? I just don't want to hook up a speaker to the other wierd taps and cook it. The pimary is easy.2 plates and a CT.but the secondary has 7 taps including the common. I foolishly did not label the leads, as I hadn't planned on using it, but now I am going to give it a go. I believe it is from the 1940s as there are no IEC codes or any other markings on it. Here's my question: I have and OT that I pulled from an Allied phono/mic amp a while back. Couldn't have done it without all your help ! Hi.once again thanks to all of you who have so freely offered your knowledge to this noob.I sucessfully built my first amp from scratch.
