 SPE – Expert 1K-FA - Series 2  
SPE – Expert 1K-FA - Series 2 solid state KW 1.8-50 MHz HF amp in very nice condition. Excellent 4.9 Star rating from 102 reviews on eHam.net. Purchased as a back-up to my Alpha 77, but never needed and has had very minimal use. This 1K-FA has had the factory update for MARS / General Coverage transmit. Includes internal tuner, manual, cables, heavy duty carrying case with handle, and original factory box with all protective inserts. 2 radio inputs, 4 switched antenna outputs, and provision for SO2R.
Would prefer not to ship, but you can come to my QTH in the greater Chicago metro area to see the amp or have a local friend come by for you. Otherwise, could supply a video showing the amp in operation with a Bird wattmeter and metering.
Can ship, or as a possible alternate, it could be delivered at no charge in early December along the route from Northern Illinois to SW Florida via Interstates 65, 24, 75 -or- 57, 24, 65, 10, 75 depending on your proximity. $2250 for everything.

 Henry 2K HF Amplifier For Sale   

Henry 2K HF Amplifier For Sale:
-
The Henry 2K is a monster HF amplifier,
covering 80 thru 10 meters.
-
It uses a pair of Eimac 3-500 Z tubes,
to easily produce full legal limit (1500
Watts) with about 100 watts drive.
-
It is a single stage amplifier designed
for SSB, CW, FSK and AM operation. It is
a very, very rugged, heavy duty amplifier,
with an extremely rugged power supply,
with a huge power transformer, choke input
filter, and oil filled filter caps. At over
150 pounds this amplifier is "built like a
tank".
-
Of course all of this is in a very nice floor
console, with the power supply in the bottom
portion, and the RF portion in the top.
-
This one works like it should. With full
power out of the exciter, it produces
1650 watts into a dummy load.
-
Cosmetically it is very close to perfect.
I can not find a scratch or defect on it.
-
Buy it with manual for $1200.
-
Since it is 150 lbs, it is obviously
pick up only, near Ocala, FL.
-
Thanks. 73,
Ken Simpson, W8EK

 SPE Expert 1.3K-fa Price reduced  
This amplifier is in mint cosmetic condition, and it is working perfectly electrically. It has the internal antenna tuner option, original carry bag, and box. It currently is setup for 240V operation, but it will work on 120V by simply changing the plug. When operated on 120V the output is approximately 900W. It will put out 1300 to 1500 when SSB and CW on 240V. It is limited to approximately 500W on FT8. I am currently operating the amplifier with Flex 6400 which is advertised in a separate ad. I would sell the amp for $2900 shipped, $2800 picked up, or together with the Flex and amp/radio interface cable for $4000. I am located in Brownsboro, AL which is a Huntsville suburb. Come by and see them being used! Could bring to Stone Mountain Nov 1 73, Craig

 FS: Alpha 8410 Amplifier - NICE  
Super clean, low use and to the best of my knowledge fully operational Alpha 8410 amplifier. This amp has the two 4CX1000’s. It easily did the legal limit with around 25 watts input. https://www.eham.net/reviews/view-product?id=7553
I would like to sell the amplifier to someone familiar with the operation of a manual tube type amplifier. I do not have the original cartons and I DO NOT WANT TO SHIP the amplifier, but am willing to deliver or meet someone up to 100 miles from Eau Claire, WI. I would like $1500.
Thank You!
