    I also have a spare which came from W9XRT who didn't have a reactor for it so he sold it to me last year for $100. I hope I don't have to use it, but it's nice to have one. Is 1690 the number for the transformer or the reactor? I can't remember. The RCA reactor I use is a XT something, 40 or 45 Hy. Don't hold me to this but I have some idea from somewhere that both are rated for either 350 ma. or 500. RCA also used that transformer in a 5 KW rig. The rig had a 250 watt driver and the transformer was on that, I think in case the station either went to 250 at night, or as an aux in case the PA crapped out.

    depends on the unit of measurement.

    XT-1690 is the transformer. The reactor is rated at 350 mA, about 40 Hy IIRC. I traded mine off for the BL-40 audio limiter; didn't need it since I was already using the UTC 50 Hy 500 mA reactor. Don't recall the part number for the reactor.

    Right. Instead of floundering along with my memory I got up and got out my transmitter notebook and found what I'd written about the iron. The reactor is the XT-2282. 45 Hy., 120 ohms, 2.5 KV, 350 ma. Everything you posted about the transformer is correct. The current rating is unknown. I ass-u-med that it was also 350 ma., but the two were not really paired by RCA I think. The just look like they go together. If the reactor were made for medium wave broadcast, it would have likely been used in 250 and 500 watt rigs. I still can't get over the one Gates used in their 1T and 1Gs.

    Anyone know who bought it for 100 bucks?
