UTC A-30 450 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? --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |
