There are quite a few on eBay, going for less than USD15 from the looks of it. Go to ebay.com and search for "813 tube." You may as well keep it as a souvenir. "PM" |

As someone else said, ebay is an indicator of what buyers will pay for used items. For a price on new tubes, try RF Parts. |

The plate dissipation is over a 100 watts and they list the output power as 100 watts. (0.1 KW). Course they may be running class A. I think the ones I've seen were rated at close to 3000 volts on the plate and on the order of 250 to 500 watts out depending on class and duty cycle. I used to run the legal limit with a pair in grounded grid. (Yup, tetrode in GG G). You could darn near read a newspaper from the light off the plats. One of the locals just picked up a pair for $10 or $15 each. OTOH that is about the cheapest I've seen them. As others have mentioned I'd watch e-bay and see what they are going for.
