I am having a ton of fun with the transformer kits I got. THANKS! I have learned alot on constructions and ran into a strange bird...
In an API 575 module (tone Oscilator), there was a output transformer that I removed. It is numbered API 2517. It is smaller than the 2503 and has 3 windings. Two windings measure 25 ohms and one measures 16 ohms. Which would be primary? For a preamp. would I have to place a pair windings in series for some gain?
The color on the wires are strange too. One pair is blue/white white/blue. One is Red and Brown. and the last White/brown and grey. Not sure how to tell the Hi side of each coil.
Also when I checked my transformer kit, all the coils measured 14 ohms. But CJ mentioned the primary is 75 ohms, and the secondary is 600 ohms. How does this work?
Thanks,
Joe
