Seeburg output transistor PAIR for all TSA series amps p.n. 309412 - $50 - (Lancaster, OH)

Pair of original Seeburg part number 309412 output transistors for Seeburg stereo amplifiers TSA1 through TSA10. These were manufactured for Seeburg by Texas Instruments. Germanium transistors are difficult to find today and generic replacements are very expensive. Transistors used in output stages of amplifiers should be matched for gain and the blue paint dots indicate that these are a matched pair. Seeburg painstakingly inspected and tested these upon receipt from the manufacturer and coded them with the paint dots. Before replacing output devices be sure to test other parts in the output stage e.g. driver transistors. These parts have been tested with a precision transistor analyizer. Due to the nature of solid state devices no returns can be accepted. If you have questions, please contact me thruogh ebay.
