 FOR SALE/TRADE Ameritron AL-811H w/572bs  
Here is a very nice AL-811H Amplifier with 572B tubes. Just checked out by an RF Engineer and working properly. The 572s make this a whole new amp with regard to toughness. Absolutely no returns. If you are in Tucson I will bring it to your shack and you can check it out. If it is shipped it will be as-is no returns.
$850.00. obo
I would consider a trade or partial trade for a modern HF transceiver and can add or receive funds to make it happen. Tell me in the first email what you have in mind for both of our sake. I prefer local pick up in the Tucson area. If you want me to ship it I will deliver it to a very good shipping center and let you work with them about the shipping. I do not have the box.

 WANTED: Ameritron AL-811 AMP in W WA
I am wanting a 600 watt HF Amp, like the AL-811.
I know I don't really need it, since 600 watts is just one S-unit over barefoot. But I want to be a member of the QRO club, if only for a bit. And I don't want to pay much.
Shipping an amp is expensive and damage-prone, so I am looking for one for sale near my home in Olympia WA. I am prepared to drive 100 miles to meet up.
So let me know what you have, condition and price. Send pictures. one with a sign in front with your call and date.
73, John K7NFL

 FS: OM Power OM4000A  
Selling my OM4000A as solid state amps better suite my operating style.
The OM4000A is just back from OM Power's U.S. service center, and has had two new tubes matched by OM Power installed. It is in excellent condition with now scratches or other issues. Inside, it is bright and shiny, and is a joy to look at.
To give you a sense of the overhead this amp has, into my Alpha 2000 dummy load, I measured the following with an LP-700 wattmeter:
160m 9.1 in/801 out 13 in/1299 out / 17.1 in / 19.5 out / 25.1 in / 3268 out
10m: 12.5 watts in/2012 watts out.
Included with the amp is the OM4000A remote control unit, which allows you to turn it on/off, put it in standby/online, and also displays the power. Additionally, there is an embroidered cover to keep it dust-free. The original box and packing materials are included also.
$6300 - get it before the tariffs kick in. An OM4001A (the successor to the OM4000A) is currently $9,300 at DXE.
Thanks!
