Title: DX100 driver transformer help Post by: Jim KF2SY on June 12, 2006, 12:57:00 PM Hello all,
Friday nite zorched out the audio driver transformer...was hitting it a little heavy ;-) Any way was looking at the Hammond P-T124D or the P-T124E as possible replacements. Both available at Antique Electronic Supply. Anybody ever try these for this rig in that application? Are they suitable? Thanks, 73 Jim KF2SY Title: Re: DX100 driver transformer help Post by: WD8BIL on June 12, 2006, 01:27:38 PM Jim .... the 124E is a good replacement for that application.
I have one in the Viking 1 and it's worked FB for a few years now. I also know half a dozen other Apache, Viking 1 & 2 class xmitters with 'em in.

I can't remember what the turns ratio was but I replaced mine with a Merit I had in the junk pile. I was seriously considering going the phase inverter/resistive coupled route. That may be worthwhile to investigate.
