In Reply to: RE: Help: Hammond 272DX 125 Tap not working, but 115 is working. posted by Triode_Kingdom on September 23, 2016 at 15:46:28
I just checked, all three wires DO have continuity. Any other thoughts?
2 alternatives in case the 125V tap is not working:
1. put in a #47 light bulb after the fuse to reduce voltage by 6V.
2. get a new transformer. In your opinion, Mr. Triode_Kingdom, is the power transformer a critical component that should be updgraded from a Hammond product? Or is Hammond as good as it gets? I have Hashimoto OPTs and wondering if a Hashimoto PT, or other brand, would have sonic improvements.
Follow Ups:
Did you unsolder all the leads before measuring with the ohmmeter? If so, you've connected something wrong. Inserting any resistance in series (like a lamp filament) will degrade regulation. Some people use a bucking transformer, which has less negative effect. If you want to discuss Hammond vs other brands, that should really be a different thread.

Buy Chinese. Bury freedom.
Statistically, it's most likely you made a bad solder joint. Just sayin' ... :^)
Paul, you were correct. Except, it was a bad solder job by Hammond. See my update to the original post.
unplug EVERYTHING and check resistance of primary across white and black. should be 2.869 ohm + or - 20% at room temp, according to link
