Acrosound TO-300 output transformers. 6600 ohms plate to plate, 4, 8, 16 ohm secondaries, 20 watts, +/- 1dB 10 - 40kHz, 75ma per tube,
For Ultra-Linear operation of KT-66's, 807's, 5881's and Ultra-Linear conversion of Williamson type circuits. Cosmetically challenged.
The cases are pretty scratched up and one of them has cuts on the mounting tabs. The leads are long and look like they have never been cut or soldered. However some of the leads have damage to their insulation. I tried to document this in the photos. Electrically they work fine. I tested both with a function generator and oscilloscope. One of the pictures shows how a square wave looks on at 1kHZ. $80
