Vintage Single Ended 6T9 Tube Qty 2 Output Transformers & Power Transformer, Tested.
The 6T9 is a compactron tube and has a high-mu triode and power pentode which makes it a popular tube for single ended amplifier design and build. You can find much information on the internet on these amplifiers.
This set of 1 power transformer and 2 single ended 6T9 output transformers is from a 1965 Wollensak reel to reel tape recorder. The power transformer originally powered 2 - 6T9 output t...ubes and 2 other tubes. See the last 2 photos which show the amplifier schematic and a close-up of the power transformer, it shows the transformer leads color coding and the high voltage value obtained (320 VDC).
Note the power transformer will need "L" brackets to mount the transformer, unless you cut a hole in the chassis to fit the bell sheetmetal
The amplifier that this power transformer is from used silicon rectifiers for the DC high voltage, so there is not a 5V winding for a rectifier tube.
The schematics in the photos show the wire color coding.
Power transformer dimensions (approximate):3.0" width (bell side dimension)2.3" depth2.7" height
The pair of audio output transformers were designed for use with the 6T9 tube in a singled ended design with the secondary driving an 8 ohm speaker.
Audio output transformers manufactured by Triwec.
Audio output transformer dimensions (approximate):1.65" wide (not including tabs)2.0" depth2.0" height13.8 oz each
The transformers are in excellent cosmetic and tested condition. Like many early tape recorder amplifiers, they were lightly used.
Purchase with confidence, transformers may be returned within 30 days for a full refund (including all shipping costs) if you are not fully satisfied.
