This is 2 Vintage Tube Pieces: a Hallicrafters HT-40 & some type of Vintage Tube Homemade Amp. The Hallicrafters power light comes on but no tubes light up. The other one has a power light and the tubes do light up. No further testing has been done. I really don't know anything about them or what they are used for. My guess is something for ham radio or CB. They are sold AS-IS. Price is $100 for both. PLEASE NOTE, I HAVE BEEN HAVING PROBLEMS GETTING MESSAGES THROUGH CRAIGSLIST. IT IS BETTER TO CALL. LEAVE A MESSAGE IF I DON'T PICK UP. THIS IS A LANDLINE, SO NO TEXTING. Please email or call Todd at 717-691-78zero6. No calls after 9pm please. See my other listings for more electronics, collectibles and stereo equipment. Search "7806" on Craigslist. IF YOU SEE THIS LISTING IT IS STILL AVAILABLE. I DELETE ALL MY LISTING AS SOON AS THEY ARE SOLD. Will also trade for vintage stereo equipment.
