Transformer ID & Specs Sheet Help

Trout · 17th January 2006, 02:47 AM

Hi Guys, I picked up this nice looking piece of iron but I really need a specs sheet.
Theres a couple extra wires I am not sure of,
Based on the ID code 138035 I am pretty sure its a Stancor,
But The only other number" KA 5361 B" is not listed in the 1961 catalog i have. This is a fairly large PT, I am guessing about 6-8 lbs.

Yes, 138 is Stancor. Probalby an OEM number though... Standard color code? Black wires will probably be a few ohms, thats 115V primary. Red / red yel is HV, yel is rectifier filament, grn 6.3. Hook it up and see... You can estimate the HV secondary rating from winding resistance Estimate the filament capacity by loading it with a 6AS7 or two (2.5A each...)
