Acom 1000 HF+6 Amplifier: Original owner, bought new early 2018 from DX Engeering. OEM triple boxes/inserts, fuses and printed manual. Very powerful original 4CX800A tube. Serial #170144, perfect condition, needs nothing. No CW, AM, digital or continuous key downs. SSB phone use only, used in the range of 500 to 700 watts a few times a week when the DX is running. Never any issues, lots of protection circuits. Currently set for 240 Volts, can be changed to 120 with instructions. Unit is heavy, in the 56 pound range and has only been moved one time. No smoke, animals or items stacked on top. I have ordered a solid state amp, mainly for the reduction in weight, so the Acom needs to go. Lower-48 USA only and will ship UPS insured and tracked, or a pickup or will drive 100 miles to meet. Price is $2450.00 cash, USPS money or PayPal. Call anytime day or night.; Listing #1561468 - Submitted on 10/22/21 by Callsign NC4Z, Modified on 10/23/21 - IP: c-107-3-255-18.hsd1.tn.comcast.net; Click Here to Email -- Click Here to View Picture -- Send this Ad to a Friend
For Sale; Amplifier Tuning Pulser: FOR SALE; Amplifier audio tuning pulser/"Woodpecker" for proper and safe tune up of any amplifier or tube type transceiver. The pulser emits a pulsed audio signal into the microphone input of the transceiver. The time constant/spacing of the pulses allows you to quickly and easily adjust the Tune and Load controls of the amplifier for maximum PEP output and linearity. See the photo showing a Dentron DTR2000L amplifier putting out 1500 watts into a dummy load while the plate current indications are very low. You will likely never burn up a set of tubes or damage other amplifier components if you use a "Woodpecker" for tuning. Over 2,900 in service. $36 shipped, check or money order, No PayPal. Includes complete instructions and schematic. Lifetime guarantee. If your radio has VOX, just tell me what transceiver you will be using and I'll install the appropriate connector. (2 pin, 4 pin, 8 pin, 1/4" stereo,.206, RJ-45, etc); Listing #1560472 - Submitted on 10/15/21 by Callsign K8WOZ, Modified on 10/23/21 - IP: 75-50-55-64.lightspeed.hstntx.sbcglobal.net; Click Here to Email -- Click Here to View Picture -- Send this Ad to a Friend

FS : Collins 516F-2 275V regulator board: Collins 516F-2, LV 275V regulator
Due to the 1956 design of 516F-2 power supply for Collins KWM-2 (A) or 32S series transmitters runs on 125V AC power Voltage, the 516F-2 supply should deliver 275V Low Volt becomes 330V Plus minus during receive mode of KWM-2(A), vacuum tubes get 330V which will shorten life of tubes and cause extreme hot temperatures affect other parts. KWM-2(A)and 32S series transmitter get lot of troubles. I have a solution to keep the LV to exactly 275V either transmit or receive mode.Using 500V MOSFET and series of Zener regulators,LV is now tightly regulated which helps keep the VFO with no drift and no audio hum as it works as ripple filter.The board is 22mm x 30 mm by size, made with SMD components and can be fit to the sidewall of power supply. Price is $35 plus $5 for USPS. Send me a check to my QRZ.com address. Other Voltage output like 150V to 300V any regulated V is available by request.Ask details to ykimpower at gmail.com; Listing #1561536 - Submitted on 10/22/21 by Callsign K6HM - IP: 75-37-192-218.lightspeed.lsatca.sbcglobal.net; Click Here to Email -- Click Here to View Picture -- Send this Ad to a Friend
