New unit MADE IN ITALY by transformer professionals with decades of experience manufacturing high voltage transformers.
Improved replacement 240/120 volt dual primary export power transformer. Heavier construction, runs cooler, gives better regulation, won't buzz and hum like some originals do. Bolts in to ST70 with a larger hole on the chassis.
Also could be used to make a 70-90W mono power amp (depending on output tubes and rectifier) using the our output transformer. Secondary B+ winding is 720VCT (360-0-360) at 300mA with 55V bias tap, plus two 6.3VCT 5 amps and one 5V 4 amp tube filament and rectifier windings. Can use solid state rectifiers or any single tube rectifier with filament up to 5V at 4 amps (or 2 5AR4/GZ34 could be used in parallel) and sufficient B+ current rating. Usually 5AR4 or 5U4. Note, watch that the voltage isn't above capacitor ratings if solid-state rectifier is used!
Primary 240VAC or 120VAC 50/60 Hz.
Mounts in 2 5/8 by 3 1/2 inch (67 X 90 mm) hole, mounting bolt pattern is 3 X 3 3/4 inches (77 X 96 mm). Nice long insulated leads.
