 FS: RM Italy HLA 150 Plus  
This is a nice amp! I have used it in the past with both the Hermes Lite II and Icom 705. Works great. I just tested it out this afternoon with the 705 and made a few 5-9 contacts. I replaced the stock fans with Noctua fans for quiet operation.
This has auto-band detect and high SWR protection. My only reason for selling is I upgraded to an amp with built-in tuner. I do not have the original box, but will make sure it is packed well.
Price is $420 and includes ground shipping. P'pal please.
Thanks!

 Flexradio PGXL Amplifier - Brand New
I purchased a Flexradio PGXL amplifier a few months ago as a possible replacement for another amp that had failed (now repaired). I have decided to sell the PGXL and purchase a smaller Amp to have on hand as a spare. The PGXL is impressive with design features to support SO2R and remote use, robust protection circuits, among other things. As a downside, it is pretty loud.

Here's a video that tells all about it: https://www.flexradio.com/videos/power-genius-xl-overview/

The amp arrived brand new from Flexradio in September 2025. I tested it quite a bit on a dummy load on my workbench and used it for an hour in a contest. PGXLs are retailing for $6k, I would take $5.3k for it, with a local pickup. I'm in Irvine, California, with occasional trips to the Phoenix area. I have the original shipping boxes and will not rule out shipping if there are no local buyers.
