 ACOM 1000 w/spare tube  
This Acom 1000 was manufactured in 2016, and I have owned since 2021. This amp works perfectly with no faults and will do rated output of 1KW+
Amp has a ding on the front top right corner from previous shipping carrier damage, along with a few small scratches on top and sides. Included is a spare NOS GU74B tube purchased from and tested by Array Solutions, and a Vinyl Acom 1000 cover.
Reason for selling is that I recently upgraded to a legal limit Acom amp and no longer need. I have many other internal/external pictures as well as video of the amp in use that I can share. Amp is currently wired for 240V but can be easily changed to 120V.
Asking $2175 plus actual shipping/insurance to CONUS.

 Heathkit SB-220 This is Very Clean  
Up for sale is my SB-220. It has all modifications Harbach other than softkey. I will throw in the Ameritron AL-811 Soft Key with cables and external standby switch. This was serviced by Scott The amprepairguy.com within the last 3 years along with new Penta Labs Tubes. The face has been replaced with a new black one and the knobs are black as well. The amplifier works perfectly and is in excess to my needs, this has sat on my shelf for a little over a year. I've gone to all SDR and Solid state Amplifiers as well. I am in NJ and will ship on your dime. I accept PayPal for payment. You can inbox me here or feel free to email me at ultrahd98 at gmail.com $1500.00 plus shipping.
Enclosed is a receipt from the amprepairguy.com (I paid for the new Penta Labs Tubes and had them shipped to him and he installed them as well)
Note: This is non-returnable due to parts swappers and the complexity of the amplifier.

 Palstar LA-1K HF+6M Amplifier New Price  
Up for sale is a very nice Palstar LA1K LDMOS amplifier. It will easily do 1000 watts PEP. It is a very nice unit that sells for around $3900 new if you can find one. This includes a power cable for 240 volts (it will run off 120 volts but I don’t have that cable) and a copy of the manual. It’s made by hams for hams in Piqua, Ohio and is a current production product. My only reason for selling is because I’ve put an Icom PW2 into service. Price is $2650 plus $75 shipping. Pickup preferred or meet with 100 miles of Fort Wayne, Indiana but I would ship. It’s not very heavy, 27 pounds. No PayPal, bank check, postal money or cash only. More photos upon request.
