Circa 1977. I am original owner. Used only about 1/3 of the time.
On/off switch does not always catch, so I leave it on and use power strip with Remote control to turn it on and off...when I had it installed. Otherwise, fine. Manual would be included.
This is an interest check.
It's big and HEAVY, so postage and wrapping won't be cheap.
I was hoping for about $160 or so, plus shipping and packaging.
