  1. Default Heathkit SB-301 tube

    Hi guys, I just got an old heathkit 301 receiver that isn't receiving at all. one of the tubes is missing. I can't seem to find anything online. Does anyone know what tube this is? I downloaded a picture on line and pointed at the tube that is missing in mine. Thanks for any help.

    That explains the no audio. I can't seem to load those other pages. I'll keep looking. Thanks.

    I just did a restoration on a sb 301. That is extremly clean! I cleaned rat posion out of mine:'( I don't know the number right off hand but the manual will tell you. The same tube went out on mine and killed the recieve. I got a replacement off ebay for around $3.

    I keep kicking myself for selling my SB-301.
    Good radio and a wonderful kit to have built.
