VERY RARE !!!
Here you have a rare chance to get a complete output stage (without power TO3 transistor) for Sansui amplifier, model AU-X1. It is untested. Only what I have tested are emitter resistors, and they are good. As you can see on those high resolution pictures, the board is complete, undamaged, without burned parts.
I have NOS TO3 Power genuine Sanken transistors for AUX1 too, please look here at my web shop.
Again, I would repeat that power stage is selling without TO3 metal power transistors.
Please look carefully at six high resolution pictures, because they are part of description.
Installation should be done by qualified technician only, because it is not simple to do that!
