Hi Everyone !
I start a built of some API 312 clone for my personal use
I have question about the A262A3E from OEP ( i know isn't the best
)
So if I refer to the datasheet , to get the good ratio for a mic transformer , i need to wiring the primary in parallele ( 150ohms ) and the secondary in serie ( 25K)
In shematic I find on the web , the designer wired the 2 bobbins but in "opposite" phase , both on primary and secondary
If you can check witch is the correct one please ?
I attached , "my" version
and the other is the shematic from the other designer ( Tunca )
Thanks in advance
