Description

For sale is this good tested clean, looks NOS new (mounting feet don't show marks from bolts), I've been told this is from a Dynaco tube amp, power transformer 15 pounds, size about 4 1/2 x 5 x height 5 1/4" black wires 120V in green wires 6.3V out (no CT, run 100 ohm resistor from each 6.3V to ground to act like a CT) 3 blue wires 480VCT 3 red wires 1000VCT instead of coming from rectifiers to cap, then maybe a choke, then cap to ground, you get lower voltages and higher currents from "input Choke": rectifiers, then no cap, choke, then cap with bleeder resistor, you get the actual voltage not 41% higher, i.e. the 1000VCT and 2 diodes, and input choke would give you close to 500VDC. by the general rule of thumb transformer output about 20 watts/pound, this should output 300 watts the wire to the 6.3V is not super thick, for something like a quad of KT88s, you might add a filament transformer.
