 FOR SALE: OM Power OM4001A MARS like new  
OM Power OM-4001A MARS HF amplifier, original owner, about 2 years old, very low hours (188 hours turn on time). 100% original, never had an issue, 100% perfect working order. This was my second backup amplifier I would run time to time just to run it. Perfect physical condition, original box, crate, all paperwork including the factory MARS tune up charts. Latest firmware 3.21 installed. Most bands needs about 15 watts drive for 1500 out. 25 watts drive is 2.5 kW out, 40 watts will get you about 4 kW out + or – some. This is the MARS version, operates 1.8 – 30 MHz continuous with some frequency’s needing reduced power, all included in the MARS factory tune-up and power charts. Selling as I don’t use it enough to justify keeping it. More photos of the amp can be found on my QRZ page https://www.qrz.com/db/KJ7E
This is a 110lb box, local pickup or will meet someone within a reasonable distance. Asking $8,000 with no trades. This amp is $10,459 new at DX Engineering now.

 Acom 1000 HF AMP  
Wired for 110, have documentation to re-wire (i.e. for 220).
I have the box with it.
Local pickup only, or I will meet somewhere reasonable.
Can possible do limited test in field.
Great amp, will work into mismatch, i.e. using an EFHW.
Was replaced with a solid state, so don't need this.
Does roughly 8-900, I usually ran it low. On 220 it should be able to do 1200 per specs.
Asking $2700 may drop if it's here too long.
Cash or some sort of guaranteed payment since you will be picking it up direct from me.
Located in New Bern, NC.

 HENRY 2K4 Dual 3-500Z Peter Dahl  
Henry 2K4 with X2 3-500Z tubes.
Its heavy, its built like a tank and it uses 3-500Z tubes. Recently went through a thorough inspection and lubed the fan. Very quiet in operation in comparison to the other Henry amps I own. Solid legal limit amp, heavy and reliable. Very clean internally.
Installed is a Peter Dahl Hypersil plate transformer rated at 800ma CCS, 3300VDC unkeyed dropping to 3100VDC at full load.
More pictures or operating video clip available on request.
$1300.00 or trades on other interesting gear.

 ACOM 1000 w/spare tube  
This Acom 1000 was manufactured in 2016, and I have owned since 2021. Amp works perfectly, is very easy to tune, with no faults and will do rated output of 1KW+
It does have a ding on the top front right corner from previous shipping carrier damage, along with other small scratches on top and sides (see pictures)
Included is a spare NOS GU74B tube purchased from and tested by Array Solutions, and a Vinyl Acom 1000 cover. I operated this amp conservatively at 8-850w on SSB phone, and used on digital 5 or 6 times at only 200w.
Reason for selling is that I recently upgraded to a legal limit Acom amp and no longer need. Amp is currently wired for 240V but can be easily changed to 120V. Asking $2050 plus actual shipping/insurance to CONUS.
See link to google drive folder for more images.

 Ameritron AL1500  
Ameritron AL1500 in splendid physical and working condition. Has a genuine Eimac tube, Peter Dahl transformer, factory wired for 240V and puts out full legal limit. I tested it with a dummy load using a Telepost LP-100A as meter. I purchased from the original owner who is now a silent key and just never got around to using it. I'm listing here hoping someone can pick it up in person as I dread shipping such a heavy, fragile item. $2800
