EB-63 140w Amplifier

For Sale:
CCI EB63 HF 140w Amplifier.
2 X MRF-454 RF PA Transistors.
RF Deck on Heat sink with fan, no enclosure. The "back" has the fan on it with sheet metal on three sides directing the air flow over the heat sink fins.
RF IN and RF OUT are connected through RCA Jacks on a
side bracket. (Right side of photo) easily converted to BNC.
Requires 13.8vdc @ 22 Amps.
This is a COR (Carrier Operated Relay) amp, will key
at down to 1w CW."Plug & Play". COR sensitivity can be adjusted by
changing cap values in COR circuit. There are also
mods available to add/change this to PTT keying.
I can provide links for these.
Vey, very little use. Built, tested, put on the shelf. Was built for a SSB transceiver project that was never completed. NOTE: This is the older EB63 with the heavy open frame Potter & Brumfield relay. Current offering from CCI is the EB63"A" with cheap plastic relay and thin traces on PC board.
This amp is READY TO GO into an enclosure or your transceiver project, as it has two "L Brackets" (Removable)to mount it.
Has TERRIFIC drilled & tapped heat sink and fan.
Quality build, all around, even uses case hardened
Allen head bolts for PC Board to heat sink for reliability.
More photos available if you email me.
Unassembled PC board and parts, WITHOUT drilled
and tapped heat sink or fan sell for $140 from CCI.
Asking $175 + Shipping.
I accept MO, Bank Check, Personal Check if you wait for it to clear.
NO PAY PAL, Sorry! (Long Story)
