Ad Number:1743625
Date Placed:09/19/25
Name:Mason Sarles
Phone Number:2142934050
Callsign:K5YHX
Category:AMPHF
Heading:FS Tokyo Hy-power HL-450B
Ad Message:FS, Tokyo Hy-power HL-450B HF amplifier. Cosmetics, 9 out of 10. As seen in the picture it is clean and in very good condition. Never any issues, and unmodified. It is tested working. I have used it on and off over the last 3 years. It has never been mobile. Comes from a smoke free environment. The transistors are Toshiba 2SC2879, it uses 4 of them. Currently its output is 320 watts keydown. This amplifier has protection circuits for high SWR, over voltage, and overdrive input. I have additional pictures for serious buyers, including the inside. The build quality is amazing. Selling to the lower 48 United States only. I also have a Chinese made 80 amp, switching power supply with very heavy gauge wire I would sell separately. The cables are 6 gauge wire. Selling as is, working, all sales final. I only accept Zelle, or USPS postal money order. 950.00 shipped. If you have been looking for one you, won’t be disappointed. Contact, Mason 214 293-4050

Your Response to this Ad:

Due to the amount of non-ham scammers trying to respond to the ads, I am now asking a simple question that ham operators should easily be able to answer, but scammers may not know the answer: What is the number that hams use to represent the phrase "Best Regards"? This number is typically transmitted by hams at the end of a QSO.
Best Regards:
