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.
$6250 - get it before the tariffs kick in. An OM4001A (the successor to the OM4000A) is currently $9,300 at DXE.

FOR SALE: Swan Mark II Amplifier: I just rebuilt the power supply with the Harbach rebuild which included replacing the mercury relay with a heavy duty standard type relay. Went through the unit and replaced worn or hardened gromets, fan power cords etc. The pair of Eimac 3-500s are very clean and score a 9 out of 10 on a thorough visual inspection and produce 1300 to 1600 watts with 100 watts drive (depending on band). Fully tested output is super clean. cosmetically 8/10. Lubbock, Texas area will drive 100 miles. $850.00; Listing #1741752 - Submitted on 09/02/25 by Callsign WR5O - IP: dsl-76-77-28-102.networklubbock.net; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
