SIT audio drivers / voltage amplifiers (or 'low power' outputs).
They are custom made in the good old days, specifically for audio as drivers, so the part
number is irrelevant here (besides, I don't want to give any ideas to the counterfeiters...)
Case TO-3 (metal), 200V, 1.5A, 42W, good mu at normal voltages, good for 'two stages' PA, made to drive even more powerful SIT, than Sony's. Very linear, output impedance easily can be 100-150 Ohm. This is all the info you need.
Can spare a few, at $16/ea. If you want them, contact me with the quantity.
