Title: UTC Mod xfrmr S-22 ratings Post by: WB6VHE on May 19, 2005, 04:00:07 PM Greetings!
Does anyone have, or know where to get, the specs (max voltage, current, etc) for the UTC S-22 mod xfrmr? I got the connection info from amwindow website, but haven't been able to find anything else. A copy of a spec sheet would be wonderful! Thanks in advance, and 73, Title: UTC Mod xfrmr S-22 ratings Post by: Ed - N3LHB on May 19, 2005, 10:06:34 PM I have a few copies of UTC catalogs, the only spec's mentioned for the S-22 is that it is a 250 watt mod transformer, no specs on max DC volts or current.
It does mention that the secondary "carries class c current" (no value), so whatever 500 watts works out to be on your final would be the limit of ma that the secondary permits, since mod power is usually half of the carrier.

at 2 kV; plus, specs for other tubes also interesting. Thanks again! 73, |
