 AMPHF - FS: COLLINS 30L-1 HF AMP.  
For sale--COLLINS 30L-1 hf amp. 80 thru 10 meters. SSB or CW. 4x 811A tubes. Wired for 120VAC but can be changed to 240VAC. Works as designed. No mods done that I know of. I see 560 watts output into a dummy load with 50 watts of drive. Collins claims with 70 watts of drive you could get 1000 watts input in SSB mode. This amp is very clean, inside and out. I have 2 different manuals for it that look original to me. Winged version. I will not ship this amp--you can pick up here at my QTH or we can meet within a reasonable distance from my QTH.
Asking $400.00 cash.

 AMPHF - FS Collins 204F-1 3.5 KW Amplifier  
I am selling my Collins 204F-1 amplifier. This amplifier uses a pair of 4CX-1000 tubes. It will tune 2 to 30 MHz continuous. Collins reports the duty cycle as 24/7, at 2.5 KW. This amplifier is in very good condition. It was built for the military with heavy duty components, and vacuum relays.
Much better built than anything sold in today’s market. No displays, IC’s or proprietary software that becomes unobtainable. There is a lot of information on the internet on this amplifier. Pick up in Northwest Oklahoma. It is big and heavy. It is not weak and unfit! Sold as is, working. Selling for 3500.00. Cash, ZELLE, USPS money order accepted once the money orders clear my bank the amp would be released. Mason, K5yhx. 214 293-4050. More pics on request.

 RADIOHF - Collins Round Emblem Station FOR SALE  
For Sale: 75S3C, 32S3A, 312B4 & 516F2 (as dog-house on leash w/o cab). Round Emblem MARS units recently fully serviced. The 516F2 has been completely rebuilt updating it with HV regulation, SS relay, as well as buck boost on the AC input. The 75S3C w/SSB & 500hz CW filter serviced, aligned and thoroughly tested. Similarly the 32S3 was serviced, the dual band crystal platform added to update it to a 32S3A, and the speech compressor added. The 32S3A is 100 % except no drive on 80 when used alone. Probably a ground problem; we just could not find it. The reason we tink it is a ground issue is because using the 75S3C in transceive mode w/the 32S3A, all bands are 100%, including 80m. The two main S-Line cases need cleaning & repainting (over-spray ?). Everything is packed and ready to ship. Make me a fair offer. This is a rare opportunity to buy & use an S-Line station that works. See my QRZ page: https://www.qrz.com/db/W5JV. SERIOUS INQUIRIES ONLY.

 POWERSUP - FS: 275V regulator 4 516F-2 and PM-2 PS   
Due to old 1956 design of 516F-2, or PM-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 heat problems. 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 $40 plus $6 for USPS. two or more it has to be shipped by priority, price is $13.check to my QRZ.com address.Other output V,150V or 250V or 300V if needed.
