Selling a used Triad 7795 Power Transformer with 940 VCT HV, 2 x 6.3 V and 5 V windings.  This was probably pulled from military gear because it has two primaries; 105 and 95 VAC.  I hooked it up to a variac and bench tested it with a diode bridge rectifier into a 12 Hy choke, 10 mfd cap and a 75K bleeder and got 925 VDC.  There are two heavy 6.3 volt windings along with one lighter green pair which is taped so I couldn't confirm their voltage.  There is a brown pair that reads 6.3 volts.  I assume it was used for pilot and dial lights.  It's light duty.  There is also a 5 volt.  I don't see any center taps for the filament windings unless they are the two green unused wires.  The core is 2 1/2"  so this is heavy duty...probably around 200-250 ma.  Just for kicks I ran 120 into it and got 1080 DCV out.  I intended to use this for an 807 modulator but decided to go with 811A's.  Asking $35.00 plus $12.35 Flat Rate shipping, USA.  May consider a trade for an 811A.  Contact me direct:  W9ZSL@yahoo.com thanks & 73!  Mike
