Today's Mystery Guest (RCA CTC-4)

[Phil Nelson]

Yes, that was my question -- should this xfmr work at all, given its component differences and the circuit differences between the earlier sets and the CTC-4? (The CT-100 has the same circuitry shown in the CTC-2B snippet I included a few posts ago.)

I sent a follow-up email to Moyer asking if they happen to have a data sheet for the Miller 6025 xfmr, which purported to be a match. They emailed me a scan of the data sheet, showing that the Miller xfmr is a match for the Meissner part -- not the CTC-4.

One way or another, I guess I'm destined to take the old transformer out. If breadboarding the new one doesn't work, then the last resort may be trying to rewind the original. But I could try the original in the breadboard circuit before attempting a rewind.

I have these parts on hand. Is this what we're talking about building?



I'm hoping I can tap the 6.3VAC filament supply and B+ supply from the power/audio chassis of my Admiral 24C15 B/W set.
