The 120V primary leads are both black, and then there is an orange ground wire. Many transformers have a black and white primary to correspond to the hot and neutral 120V wires, respectively.
Does it matter which 120V black wire goes to hot and which one goes to neutral?

The polarity of the primary leads does not matter.

Product Reviews
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.
