Why did u have to go through digikey..and not directly with hammond / dahl ?? ??
NO hv sag at all, that's superb.?
IMO, whatever the B+ is? with amp keyed, and sucking normal idle current is the real no load B+.? ?It has to idle 1st, before you ac apply drive.? ?I really could care less what it is in RX.? ?But that has it's limitations.? Like if EBS is used, etc.?
Alpha? 91 / 99? xfmr's are failing? ?at a high rate these days.? ?Same deal with the older ACOM amplifiers.? The issue is, they have a total of 5 windings on the secondary side..... and in all the failed units, the high voltage winding, is arcing to a lower voltage winding.? ?The insulation has broken down over the years.?
Dahl never went cheap with the insulation..and neither did Hammond.? I still have hammond plate xfmrs made in the late 50's that still function, even with floating CT's....and also stuffing 247 vac into the 210 vac pri.?
