Our users rate Reverb
One (1) fully 1.00 kHz AC tested and guaranteed vintage tube amp output transformer. AC testing using an oscilloscope allows us to find and reject transformers with noisy outputs, which a simple resistance or continuity test will not reveal. Made in USA in 1959 by Woodward-Schumacher for Webcor. IEA date code may vary, since this is a bulk listing of the OEM specification. Please offer $2 extra if you'd like us to poke through inventory to select a certain manufacturer or year. Otherwise, we'll grab the first one on the shelf. A typical IEA code for this model is 606940. Weighs 0 lbs 10 oz. Center-to-center bolt spacings 60 mm, and height of casing is 41 mm. Quantity sometimes available - please enquire.

Please see the image of an original schematic using this model, for one possible application!
Using a 12V_pp, 1.00 kHz input to the primary coil, we have verified these connections for this vintage transformer:
The turns ratio (pri:sec) is 21:1, leading to an impedance ratio for the main secondary coil of 460:1.
