Hi all. I have an Atlas model 7686658. They're for sale on E-bay. The gentleman there said he uses them for Hi-fi...So far here's what I have:
it's a 1+1:?+?, the cover shows this, 2 primaries and 2 secondaries...The DCR is 300+300:1.5k+1.5k. It seems to be around 1+1:2+2 judging by putting a sine wave on the primary and watching the secondary....When I hook up the primaries in parallel, and hook up the secondaries as a center tap situation, I get opposing waves that are almost twice the amplitude of the input signal.
Response seems good, it behaves the same at 50Hz as at 18khz, I'm just trying to figure out what it actually is as far as impedance, and if it's safe to use as an input phase inverting transformer for a 300b build.
Any help is greatly appreciated, thanks guys
