 YAESU >>FAS-1-4R<< for FL-7000 Amplifier  
This “nearly impossible to find as NEW” remote antenna selector has never been installed. It comes with all you see in the photo; mounting hardware, rubber PL-259 protective boots, paperwork and about 90’ of control cable (not shown). If you are running one of these classic FL-7000s amps and want this shipped to your door, I’ll take $280 via money order, PayPal, Venmo, or even your personal check.

 RM Italy HLA305V  
RM Italy HLA-305v HF amplifier in excellent condition. This amplifier is ideal for low power HF transceivers (< 10w) to get about 200w out. This was used with a Hermes Lite 2+ SDR and Square SDR, which are ~5w output.
DX Engineering is selling these new for $860. I'm asking $550 shipped in the continental US. I prefer Zelle or Venmo for payment or cash if picking up in SW FL. I'll also be at Hamcation in February. I'll gladly discuss via phone for extra assurance. No returns.
