[GreenKeys] power transformer

[Sam Stinson]

Found this one on ebay "Basler Tube Amp Power Transformer" a simple search
for should turn them up. Probably sold elsewhere but I didn't spend any
time to look. Cost is $9.66 + $6.40 shipping for me

"Item is one tube amp power transformer for converting 240 volts AC into
6.3 volts AC, 330 volts AC, and 28 volts, center-tapped. Transformer is
labeled 400 volts, but actual output seems to vary from one to the next,
most are around 330 volts.   The maximum output current of this transformer
is not known. This transformer is made by Basler and has part number
BE32900001. This transformer measures 2.5 inches tall by 3 inches wide by
3.75 inches thick. 6.3 volt secondary is 4 amps, other currents not
specified. Will not work with US mains current. Mounts through 1.5 x 2 inch
hole."
