Purchased new in the mid 80's and has been used quite extensively. One of the channels will sometimes cut out requiring one to fiddle with some of the knobs and buttons to get it back. Nothing that a thorough servicing wouldn't fix or perhaps a small project for the DIY'r. I'm cleaning up my basement and did not feel right about tossing this thing in the dumpster before offering it up to someone who might be able to make use of it.
I'll run the karma for a week and make a draw next Wed Oct 28th after 7pm.
If you want to paypal me the shipping for FedEx ground from 43202 you can but not necessary. I've still got the original packaging. It measures 20x13x7 and weighs 11lbs. Best of luck!
