 RM Italy HLA 300 mobile HF Amp  
Due to some life changes, I have decided to not put HF in my car.
RM Italy HLA3000 300-Watt mobile Amp, both Hi and Low drive. Hooked to the IC-7000 with 15 Watts Drive ran right at 300 Watts.
Price is $550.00 plus actual shipping
I do use pirate ship for the best rates and will not ship without the insurance.
As always, I test everything before it leaves, but due to being used equipment it comes with no warranty or returns.
We can discuss payment methods when we talk on the phone, which I highly encourage.
Thank you!

 Ameritron ALS-600 Amplifier  

Ameritron ALS-600 Amplifier. Rated 160-15M, 600 watts PEP, 400 watts CW. I do not believe this one has the 12-10M modification, but have not opened it to check (the AUX position is silent on receive, indicating that the mod has not been installed). Amp works and and appears to be operational, but sold as is. $895 net to me. Will ship at your cost, or pick-up in St. Louis, MO. US only. Lou, W0FK

 Palstar LA-1K LDMOS Amplifier (pending)  
*** SOLD PENDING PAYMENT ***
.
Like new Palstar LA-1K amp bought last year. Very light use. Runs 1200-watts with 50 in.
.
Current new price is $3,795 with a 3 month wait. Selling for $2,800 shipped CONUS.
.
Palstar LA-1K features three SO-239 (UHF female) antenna output connectors, phono keying and ALC connectors, instant band changing, T/R Vacuum relay, and a "Pure Signal" output. Although not required due to RF sense band changing capability, transceiver interface connectors are also provided on the rear panel. With its built-in 50Vdc, 42A power supply, the LA-1K operates on 120 Vac at 15A or 240 Vac at 10A.
This works perfectly and matches the HF Auto, also has Pure Signal coupler for Anan and 8000 series Flex.
