I have 2, that is right, 2 Panasonic DT-690 "Platinum Colletction" boxes for sale.  Bi-Amp (50 watt) and 3-way speaker system makes for a excellent sounding box with very low distortion when volume is up. Has dual-cassette and CD player. Lots of features such as high speed editing and auto-tape selector, etc. Has 4-band graphic equalizer which works very well. The first one is missing the main volume knob and the other is missing the Panasonic logo on right side. . Also, the right hand side tape door needs fixing. I cleaned the tape heads and used some canned air to clean the tape deck wells on both.

Asking $150 obo for both plus postage.  No remotes for either.
