The brand and model of the unit is a Gelhard GXR230. Can't find much about the brand but the deck looks to be high end for the day. The only real info I can find is this literature from this link.
Gelhard Auto-HiFi '85
The product lineup looks impressive and made of quality stuff. Looking through the literature it seems that the deck I have was the third highest model back in '85.
PICS:
Asking $150, I live in Toronto but I'm heading down to DC/MD for a few days next week and I can ship from there. I leave wednesday Sept. 12, so I'll have to know before then if interested.
