You are right, I screwed up, and it wasn't so you could show how petty
and insecure you really are.

If you think your rudeness is somehow humorous, you don't know the
definition of humor. But perhaps you'd like to double-down, dig
yourself in deeper and explain...

Get yourself some counselling on your place on the autism spectrum.

It might help, a bit.

Suicide is also an option.

Nobody alive would miss you.

Few things are more pathetic than a bully who lacks the power to
intimidate. Few things are funnier than a bully who lacks the power
to intimidate but fails to understand their limitations - thanks for
the laughs.

I was looking for a 120-120 isolation transformer on eBay and I kept
finding 120-240/480 transformers. There are 2 secondaries on these
(connect in parallel or series). It occurred to me that I could use one
of these as a 120-120 by using one secondary as input and the other
secondary as output. I know that this is theoretically possible, but
are there practical reasons why it wouldn't work?

Also: if one of these 120-240/480 transformers is rated 500VA, that
means 1 amp on the secondary, right? I.e., 1A at 480v.

Thanks,
Bob

You can use a 120/240-to-anything transformer as a 120-120 isolation
tranny. Connect one half of the official primary to the line and use
the other half as the isolated output. Ignore the "secondary". The
power rating will be a bit less than specified because you're not
using all the copper.


Sort of. Vout will be a little low under load due to copper resistance. That could be solved by putting eg a 12v secondary in series with the output, connected right way round. But the big issue is that you won't have a level of isolation that's considered safe for many applications. For some jobs it's adequate, for many not.

Not mine. It is built from a very high power amp, around 1,000 watts per channel. The secondary at 120 puts out 127, when I load the shit out of it and it drops to 120 the line voltage drops to like 116.

I had to scrap it, the amp boards got soaked with the elements and got conductive, and the protection didn't even work and it had offset and was blowing speakers.

It came out of a bar in the ceiling and I think the roof leaked on it but they didn't own the brick and mortar so they didn't give a shit.

Anyway, the load that made it drop you 120, a 1,500 watt electric heater. I don't even want to think what one with that capacity would cost. I go it for free. I didn't charge any fee just kept it, which they were cool with.
