Saint Louis, MO, United States
About this listing
Fully 60 Hz AC tested and guaranteed vintage tube amp transformer. If you're selling to Europe, the 50 Hz compatibility switch is fantastic! A transformer designed only for 60 Hz cannot be used at rated values in a 50 Hz environment. 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 Germany. Weighs 2 pounds 13 oz. Quantity often available.One 24 VAC winding was used with a solid-state rectifier for bias and the other was used for 12.6 V heater. 6.3V also available. Check out the original schematic for how to connect to this thing. 65 mm by 52 mm hole spacings.117V in to blue wire on voltage selector (or red for 125V in!) and white below selector.Fuses not tested. These are our stock photos for this model. Some variants have vertical printing rather than the horizontal that is shown. All have exactly the same model number.
