Collins RE 30S-1 Excellent: Hello Gang,
I am clearing out the last few items of my Collins gear. I have three museum quality late serial numbered Round Emblem 30S-1 amplifiers. Two of these are in museum quality condition, and the third has a relatively scratch about 12 inch long not to the metal on the right side.
These were last fired up about ten years ago and have been stored in a dry smoke-free environment.
Time for these to be granted a new home.
I am selling the two perfect specimens for $1,200 each, and the one with the scratch for $1,000.
I also have four NOS 4CX-1000 tubes that I will sell for $150 each.

Elecraft KPA1500 amplifier: I have for sale my Elecraft KPA1500 amplifier. I bought it along with my K4D but have not used the kpa1500 because I do not have 220v in the shack. The amp and radio was purchased from an elderly ham and he used the set only occasionally. I am happy with my Mercury Lux and Lite amps so going to sell the KPA1500. The amp comes with all original packaging items and cables.
Price is $5100.; Listing #1744157 - Submitted on 09/25/25 by Callsign K2ZZ - IP: 104.28.204.176; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
YASEU 2500 legal limit with 10 meters: Legal limit 80 through 10 meters. Perfect on all bands and I put my upgrade signature on it. I even peeled off the original front panel plastic. This is a rare amp and delivers a near KW on all bands including 10 meters.
I performed all tests and invite any and all to come pick it up in Placerville Ca.
I am asking 950.00 pick up and see it on the air all bands, or if I have to ship it we will send it FED X only and buyer to pay FED X pack and ship costs, so hopefully there is a buyer that can come to the qth and enjoy the showroom quality of this very rare yaseu amp.
it belongs is a museum.

Ameritron AL-572 Southern Californa: ** Still looking for local buyer **
I have an Ameritron AL-572 amplifier (serial number 11473) for sale. This amplifier has been my backup for the past 10 years or so; it has been used very infrequently. I tested it briefly and it was putting out 1000 watts on 20 meter CW with about 70 watts of drive. It is in good physical condition. It is working but due to its age I am selling it “as is”. It is currently wired for 220v AC but can be rewired to 120V as an option.
I don't want to ship the amplifier and am offering it for local sale for $1000. If I cannot find a local buyer I will be forced to consider shipping the amp. I have the original box.
