(EQP) SB315B/U Dittmore-Freimuth Corp control panel. I'll bet you don't have
this key in your collection!
You're really up town with this one. Separate gap and tension controls
top side. Add to that a 1/4" jack for I/O that wires directly to the key. Then a jumbo
red pilot lense wired internally to the toggle switch with an optional resistor
for 115v/ 230v optional wiring. 5-1/2" x 6-1/2" x 6" high.
All saltwater sealed. New, never used. Only 3 in stock.
