Heathkit SB-301 tube

[N2DBQ]

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.

The audio output tube.
Can't remember the number off the top of my head sorry.

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.
