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. A signature will be required. The item "Vintage McIntosh MI-200 A-109 K-107 Mono Monoblock Tube Amplifier + Power Supply" is in sale since Wednesday, July 31, 2019.
