Sola 8592 Transformer 2060-0-2060 V Vintage Power 10kV Ignition Transformer 23mA Tested HUGE 11 lb Tube Amp Project 1950s

Fully 60 Hz AC tested and guaranteed vintage tube preamp transformer. AC testing using an oscilloscope allows us to find and reject transformers with noisy or lossy outputs, which a simple resistance or continuity test will not reveal. Our testing also ensures that you have access to the wires and that they are bundled sensibly, eliminating the "discovery phase" (see below!). Made in USA in 1950s by SOLA. No IEA date code found. Weighs 11 lbs 8 oz. Bolt spacings 150 mm by 63 mm. Quantity sometimes available - please enquire.

Here are the verified connections for this transformer:

Input: 117V

Outputs:
4120 VAC center tapped

DO NOT PLUG THIS IN UNLESS YOU KNOW WHAT YOU'RE DOING. Secondary Mid-point grounded to case. UNTESTED DC supply unit that is attached uses only half the transformer!

We use a standardized wire identification scheme featuring bright cable ties. In case of any ambiguity, 117V input will be wrapped with a black cable tie, red is high-voltage, yellow is 5V for rectifier, green is 6.3V, blue is 12.6V, white is 117V out for 220V input or tubes with series heaters, purple or grey is a second (or third!) 6.3V output. The voltages run a bit higher when run at modern AC levels instead of the 117 VAC that was specified in the 1950s and 1960s. Serial number T-1272.
