These came out of a Tektronix lab and were in operation until fairly recently. I brought them up slowly on my variac and it passed audio fairly well. There is some minor hum and a little distortion at higher volumes so I'm sure they will need a full tune-up.
The power supply AC cord should be replaced as well. This will make a wonderful addition to anyone's collection. I will also be listing an additional MI-200 Power Supply.
