Up for sale is a Vintage 1947 The Hallicrafters Model S-40A Shortwave Amateur HAM Radio Receiver. This is a receiver only and cannot transmit frequencies. Seems to work but i don’t know enough to thoroughly test. Turns on and the backlights work great. All of the tubes light up. I can hear stations faintly coming in through the speaker while tuning through them. There is a little bit of crackling in some if the knobs which means the contacts will need to be cleaned. If you have any questions please feel free to contact me. Thanks for looking.
