 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

 FS Acom 2000A  
Selling my Acom 2000A with spare set of 4CX800 tubes.
I purchased it new from Array Solutions. It is in excellent condition, I have not used it very much, it IS the quietest amp I have ever used in over 60 years of hamming. I added the muffin fan too and it did not add any noise. It puts out full power plus. Local sale and pickup only. Located in the Minneapolis St.Paul metro area.
Price $4,500. That's four thousand five hundred USA. Email me with questions and tnx for looking.

 HENRY 8K PLATE TRANSFORMER  
Henry 8K plate transformer. part # Magnaspec 150400. Its a HV beast at 125 lbs so no shipping unless you pay for shipping and pay $50 to build the small crate to successfully ship this monster. Im well versed in shipping transformers and "heavy iron" but I'd rather not.....hence the $50. Unit is dusty but absolutely functional.
Transformer is 5800V at 2A ratings being conservative.
$1500

 FOR SALE- RM ITALY HLA-305 Solid State  
Heres a sweet little amp that will put out 300 watts.. Used it for about a year.. Works Perfect, never had it in a Vehicle - just in the Shack.I'm a non-smoker, clean, take good care of my equipment.
.
I took a "Wattmeter Photo" of it with the KEY down on my 7600 ICOM. I used the MFJ-4245 DC Supply in the shack to power it. NICE.. I bought it NEW from DX Engineering, $789.00 they are much higher today, isn't everything?.
.
Asking $650.00 I'll pay the Shipping, also have the original Box it came with.. You won't be disappointed for certain. I will take a Postal Money or even better yet is a WALMART Money Order. Much less than the Post Office now, and less hassle to cash it!!

 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.
