 Alpha 77D  
This Alpha 77D (serial number 2719) is in decent cosmetic condition. The top cover shows quite a few scuffs and scratches, but the front panel looks pretty good. We tested it using an Icom 706MKIIG with 90 watts of drive. Depending on the band, we got as much as 2000 watts out (depending on the band). We got no power out on 10-meters, despite it being shown on the tuning chart taped to the front of the amp.
Asking $2500 plus shipping. You're welcome to inspect the amp and pick up from our shop in Sparks, NV.
