 FS Ten Tec Hercules 444 HF AMP  
This is a good to very good condition linear amplifier with separate power supply. Minimal wear on the front of the amp. Some surface scratches on the top of the amp & PS. Performs as it should. Fan switch mod & TX relay connector mod, both minor & do not take away from the amp in any way. Rest of it looks original to me. (No Band Mods) I would prefer pick up ... but if shipped, it would go in 2 packages at 55 & 25 pounds... expensive !!
Band Coverage: 1.8 - 2.0, 3.5 - 4.0, 7.0 - 7.3, 14.0 - 14.35, 21.0 - 21.45 MHz and provision for four user modified auxiliary bands.
Driving Power Required: 50 watts typical to get 500w + out.
Looking for $550.00 Can have it at Georgetown, Oh hamfest Saturday 11/1.
