Ok, I need to go on a run. I will take a look at all the info when I get back. Do not load anything up yet. The low voltage input and just the readings are safe. I have a tube pre amp I reversed primary and secondary to get my high voltage. Changed step down to a step up. Keeping an eye on the amps on both sides.
I will be a couple of hours.

That is strange how a 220v tray is in 120v device. It can be done, but OEM? Still, it is 500 va. Voltage x current = power (excluding power factor), will be the same power, watts, on primary side and secondary. Inversely proportional, voltage up; current down: voltage down; current up and power remains constant, unless you exceed it .(500VA).
Problem is you don't know what each winding is rated for. People who make these do a high-pot test on them and it is a destructive test, but hell, they got more. The test tells them how much current the wordings can take before the insulation breaks down. Then they reduce that value to a safe operating va. The voltage is dependent on type and how many dips in the varnish the transformer takes, ( not many in China, HA).
It is a crap shoot. So you have to ask your self, is it worth the trouble to have the extra weight of the transformer, or am I a DIYer, and smoking a few components is part of the hobby... Or I fell lucky.

But they run a test on them to find all the limits, and you do not have them.
Try and contact them. Most are happy to help.
Who, xformer mfg or HTIB mfg? xformer is chinese.... can't even find a website for their company, let alone contact info
Go for it. Just don't do a permeant install.
But, you do understand the winding ratio. Voltage in and voltage out. The 120vac, and the 32vac, and the26vac.
I have ran into extra wires on the primary. They were taps to compensate for higher or lower voltages. Some regions have 220vac, 240vac or even a bit higher or lower. The Adcom amp I gutted had these on the transformer . They could only be changed inside the enclosure, but some have a selector switch on the outside.
