Also the volume and bass pots are upside down so is at 2 o clock half 6. Tube compliment: Millard IRC gz34 5ar4 6eu7 x2 sylvan unknown 12au7 I figure the alone is worth at least 40 and tubes are 90. Brought it up on a Mauriac and works loud clear.
I did some light cleaning on easy to reach surfaces so you can see the chassis is in pretty good shape. Even the red power indicator bulb works. I cleaned the tube sockets and exited pots. That's how I came up with the price.
That being said I would not use it regularly without replacing the capacitors for reliability or quite frankly even power on a Mauriac.
