I was lookng for a potted power transformer and bought this one but the B+ voltage is too high for what i wanted it for . It's 600-0- 600 volts AC , two 6.3 volt windings and one 5 volt winding and wieghts 17 pounds .
This would be a good power transformer for four 6550's or EL34's with a choke input .
For those who don't know the KS number is a Western Elecric part number
$90.00 + shipping in a flate rate box for $12.00 in the US
It 5" X 5 1/2" x 4 3/4"
Would consider trade for a 350-0-350 volt potted transformer , with filament windings .
