Description

NOS Power Transformer 100 Watt tube amp. dual primary . Condition is New. Shipped with USPS Priority medium flat rate box This is a transformer for a tube amp. project. I used 4-6L6's for 100Watt output. The temperature rise was insignificant at full power and I do not know the VA but I am sure it is more than 100W. It has a Copper Flux shorting band. Dual Primary. Its Secondary Voltages are Red to Red 170V AC.--Blue to Blue 33V. AC. -- Green to Green With Center Tap. 6.5V AC. and Yellow to Yellow 6.5V.AC ALL VOLT VALUES ARE UNLOADED. Distensions are 3 1/2 x 4 7/8 x 4 1/4 high. Please E mail me with your questions before you bid. I have used this part in production of a guitar amp. using a Voltage doubler in main B+ supply for 480V.DC Blue winding is for negative 46V. bias. The Yellow winding can be put in series with Red being careful of phasing to Tweak the main B+ winding by another 18VDC. I can fit three of these in the medium Flat rate box.Thank you. IT HAS THE OLD FRAGILE CLOTH COVERED WIRE THAT WAS CHAFED. i PUT TUBING ON THE PRIMARY WIRES SO AS NOT TO HAVE ANY SHORTS.
