- AMPHF - FS: SG-500 Amplifier with PS50 psu
- Pickup only in 28150.
I've been using it with my IC-7610 both CW and SSB plus I tested it with my little Ameco AM transmitter. With around 30 watts input you get between 500 and 600 watts out as measured on the LP-700.
The amp is switch in line via RF. When your TX puts out some RF, the amp senses it and switches automatically. Band selection is also automatic. The manual (included) tell how you can physically interface this with an SGC transceiver for manual bandswitching but for other rigs you rely on RF sensing.
Price $350 picked up here in Shelby NC.
As you can see, I've put a jumper wire from the PTT to Gnd. This is necessary for RF to trigger the amp properly. Yes that seems strange.
There is no fan so it's very quite and hardly gets warm during use due to the huge heat sink underneath.
The PS50 power supply (included) puts out 50 amps which allows 500 watts PEP and CW. The manual says you need 90 amps for digital and AM for full power.

- RADIOHF - Trade Maestro C for Maestro A or B
- I would like to trade my Maestro C for a fully functional Maestro A or B. This unit was purchased new from Flex in Sept. 2024 and of course has higher resolution than the first two models, as well as some other upgrades. It has absolutely no issues but requires an adapter to connect to my audio processor (RJ45 output). The headset jack on the Maestro C will accept a 4-pole headset plug or separate mic and headphone plugs with a Y cable which is readily available. I will ship prepaid in the original box. Let me know what you have.
