Specifications:

Size: 118 VA
Dual Primary: 115 VAC, 125 VAC, 60 Hz.
A.C. high Voltage Secondary RMS: 550V.C.T. @ 144mA
Filament Winding #1 5 V @ 3 A
Filament Winding #2 6.3 V @ 4 A

Features:

  • Enclosed, 4 hole, chassis mount.
  • Minimum 6" long leads.
  • Units can be run full wave bridge or full wave C.T.
  • Class A insulation (105 degrees C).
  • Hi-Pot test of 2,000V RMS.
  • Conservative designs - CSA certified (209651).
  • NOTE: A production "running change" has been made to the primary winding - effective with August 2009 production.

Choice #1 (115 VAC Input):
For those customers who need the 115V input - nothing has changed - simply use the White & Gray wires and tape the Black wire (see above schematic).
Choice #2 (125 VAC Input):
For those customers who are seeing too high a secondary voltage due to higher primary line voltages (roughly 125V input) - use the White & Black wire and tape the gray wire
Caution: NEVER connect power to BOTH the GRAY & BLACK wire - instantaneous destruction of the transformer will result!

Outstanding product. Works perfectly in my power supply.

I have come to trust Hammond transformers for both quality and performance. This particular model provides plate voltages, using tube rectification, well suited for the 6BQ5/EL84 power pentode which is how I am using it.
