Collins: 651S-1
651S-1 Rack Mount
(COL) 651S1-RM
Rack mount for 651S-1 without speaker. Removed from service.
$140 each
651S-1 Knob
(COL) 609-0547-001
Finger hole only for spinner knob on 651S-1.
$25 each
651S-1 Speaker
(COL) 651S1-SPK
We think this is the 3" x 5", 4 ohm speaker used in the 651S-1 rack mount. They came from Collins, fit the mount and sound fine. We do not have a Collins part number to match. Each speaker has a small flaw in the paper that can be easily repaired with nail polish. Remaining stock has tears in the cones.
$18 each
651S-1 Circuit Boards
Circuit boards removed from Collins 651S-1 transceivers and tested good (we plugged them into working radios and they appear operational). All boards sold as-is, where-is. Great spares to have on hand.
