The polarity of the primary leads does not matter.

Had a mid-70's Super Reverb with a fried PT. This was an easy drop-in replacement, worked great, correct voltages, reasonable price, will buy again!

Transformer worked great in a rebuild of a early 1968 Silverface/black-line Super Reverb.

I don't know who is making these for Fender, but they do a pretty good job. So far, I have had few quality issues at all. They are a tad generic, and the catalog is thin, and Fender tries to make a "one size fits all" out of these, but they are a quality transformer, and a good value for the price. I used on for my take on a Brown 1x15 Pro with added reverb, no tremolo and a post phase inverter cathode follower. It worked out fine. I used a solid state rectifier, so I had a good 430 volts B+. 330-335 would have produced closer to 450 volts, but it sounds good.

Perfect drop in replacement for Fender Bandmaster Reverb and similar amps. Very generous length leads too.
