Yesterday i tought i knew how transformers worked.
I wired an hammond Push-Pull tranny backwards to build a stax adapter. The impedance ratio was 1:1900 when using the 4ohms tap.
I figured that at 50K the stax headphones would then be reflected as about 26 ohms.
I feel so dumb now, sitting next to my dead sugden amp breathing burned electronics fumes.
My understanding now is that the amp saw only the low-DCR of the tranny 4-ohm winding, which was extremely low. Should i have put a resistor in series with the winding, like stax boxes have (or is it a thermistor?) ? But then again, i see somme designs without it, for example Andrea Ciuffoli's:

Can someone explain me what went wrong?
Thanks in advance.
