I have for sale an SSB Electronics SP-2000 Superamp mast-mounted GaAsFET preamp, 1 1/2 years old. Rated at 200w VOX, 750w PTT. It has Hi-Q helical coils & helical filters and is one of the best preamps for DXing, satellites, meteor scatter, and EME.

The preamp works OK, but for some unknown reason it is rusty. The preamp is contained in a weatherproof case but water must have gotten in somehow. I cleaned up the circuit board with Q-tips and alcohol. Photos available.

The SP-2000 sells new for $310 plus shipping. You can have this one for $150 shipped anywhere USA. Also would offer the SP-2000 plus cash for a 2m preamp system capable of handling 1.5 kw. I recently bought a Lunar Link and discovered the rust issue when I took the preamp down.
