Does anyone know the specs on these audio transformers. I have 2 of them and the Acrosound PDF catalog I have only goes up to TO-350.

Thanks,
Sal Brisindi

I did a quick web search and found a reference to a 1961 Popular Electronics article that called for this transformer with EL84 tubes - so it may be the 7500-10K CT primary typically used with EL84.

Why not measure them? Apply 100V at 60 Hz and measure secondary voltage(s). Impedance ratio is square of turns (voltage) ratio. So 50:1 is 2500:1 for impedance, or 10K to 4 Ohms.

Thanks Tom,
I might have to do that.
