Figured I’d offer them here before I post them elsewhere.

I have six DCOD (not the DCC flavor) detectors and a ODMB motherboard for them. These are the optimized DC detectors by Bruce Chubb, and the motherboard that they fit into. $50/shipping

Two RR-CirKits SDB-4 drivers. One brand new in bag, one out of bag, but unused. $20/pair + shipping.
