This is a Sansui model 250 stereo tuner amplifier, from an estate. I dusted the inside, wiped down the case, and hooked it up to a sound source and a speaker. When powered up, the tubes glow but during my brief testing the unit made no sound.
I repeat, the item needs repair!
It is missing several knobs, and has mild cosmetic wear/flaws consistant with its age (one thing i noticed is the "aux." lettering is missing from the function selector area?). Please look closely at the pictures provided. I have also included pictures of the tubes powered up.
