Default UTC / RCA Transformer F-1233, A-30, A-21, RCA input trans..?

450 Henry inductor. Audio type, though, not much current.

UTC A-21


Cheapo split primary matching transformer. Either end can be strapped
for 50, 250, or 500 ohms. Okay if you keep the levels low but the core
is small so it saturates easily.

UTC ........ F-1233 transformer...( RCA .."Made for RCA by UTC"


That's a house number. Since it's an F number, it's probably a filament
transformer. Apply 12VAC to the black primary wires and see.


RCA 900849-501.....Input Trans.


Likewise, what you want to know is the ratio and the loading. You're
going to need to do that by hand with a square wave generator and a scope
unless you know what this was gutted out of.

Thanks in advance...


So, let me guess, someone butchered an RT-21?
