Good question: I bought them around 1998, seem to recall the Tammura's are 5004 or something with and "F" in the name. Plan was for a 2A3 amp, so they are probably 3k-5k impedance, single ended.I don't have either 45s or 50s. Only a bunch of 2A3s.
Follow Ups:
is 6K @ 100mA, too much a 2A3.I use Tamura F-475 for my 45 which is just about right- 5K @ 45mA
The Tamura F-475(5K/45mA) is a very nice transformer for the 45 tube. You could use this tranformer with a 2A3 in a low powered circuit, but the 2A3 really deserves a transformer somewhere in the 60 mA range. I have used the Tamura F-475 for over two years in my dual mono
45 amplifier and it's fabulous.
Smoother. Cleaner. Less "grainy". But you can't imagine these attributes until you have heard them. You will give up some power and a little bass response, some "slam", but wait till you hear Dianna Krall or Allison Krauss...
