Hi all. I've recently purchased an abused KR-6600 from one of those more or less honest resellers on eBay for $152.00 + shipping. Lots of photos and one could see that the switches were broken, but the unit was "ON" and so I took a chance. Well, I hooked it up with my dim bulb and tested with phones and got stereo with no antenna. Besides that, the unit was filthy and needs all new bulbs. OK. But...the unit is always ON, the switch was broken off at its base. And I can't find one anywhere I know to look. Replacing the switch should be easy, but choosing one? Any ideas?
