One of my good friends is closing his electricians business down and asked me if I wanted stuff.
Out of everything I do not know what to do the the 208/277 to 120 50VA transformer and one 480 to 120 .1KVA transformer.
I need ideas on what to do with them.

They'd make good power supplies for low power vacuum tube equipment.

The 50 VA would power a multi-tube receiver and the 100 VA a 2-tube  transmitter with maybe 25 watts output.

You are talking about stepping the power down not up correct?
I wired the secondary and was pulling 465 out of the primary.

Right, just hook them up backwards. Us old timers used to do it with used "pole pig" transformers from the power company to generate HV for amplifiers. You never had to worry about overloading the transformer, but it something shorted out, the results could be rather "spectacular".

You did that too?  I built several amps that way.
