 Swan Cygnet 1200X HF Linear Amplifier  
Amp is complete with a variable-speed cooling fan on top.
It wasn't operated for years, so the new owner must check it thoroughly and bring it up on a variac.
The amp uses four 8950 tubes. It can be easily modded to run 6LF6/6LB6 tubes.
Copy of the manual with schematics and other docs of past repair are included.
I'll also include four supply electrolytic caps for future upgrade.
Pickup in the San Jose area is prefered but I can also ship.
Price is $250 plus actual shipping.

 Ameritron 1300 ALS Amplifier  
Amp works well. Was recently repaired by Tom Rauch, W8Ji. Has new finals and power supply has been updated. The amp comes with the power supply, which is not in the picture. Have all receipts, original boxes for amp and power supply.
Also, I will include the ARI 500 modem at no additional charge, up which allows for automatic band changes. Have been using it for 6 months with no issues at all at 900 watts. Price is $1850 shipped. Monetary payment accepted is cash, certified bank money order, Zelle. You may pick it at my QTH to see it in action. Will ship it when the money order clears
Reason for sale is that I want a Palstar amp to match my tuner, which is not included in the sale. No warranty implied, but this amp works well. Some small case imperfections are present Check my positive references if you have any doubts about the seller. Willing to do an on the air or online demonstration.

 Heathkit SB220 Amplifier  
Excellent condition amp. No unsightly switches have been put in. Sent the amp to the Amp Guy and he did most of updates. Have the receipt. Other updates were done by Wi9i. Has new Penta tubes, all Harbach updates, new capacitors, glitch resistor, slow start, can be used with modern transceivers, grounded grids, new original case, etc. This amp can be operated on 10 meters with your ham license. Have all the receipts and original manual. $1500. Pick up in Springfield, Illinois, so you can see it functioning. No issues at all with this amp and I believe it is good for many more years. Wired for 220 volts, but it can be easily changed to 110 volts. Check my references. Selling it because I want a Palstar amplifier to match my automatic antenna tuner

 FS: Ameritron AL-80A  
Ameritron AL-80A amplifier looks good and works well. Wired for 240v. Uses a single 3-500z tube. I always ran it at 500w - 600w. It would do more but I believe in being gentle to tubes. It is too heavy to ship. I am in the Philadelphia area and am willing to drive a bit to meet you. $ 595 73 de Marc K3VLS
