Just visited ebay to see how muck those old tubes I tossed might have been worth. Probably not much - 110 for $25 are listed.
Although he had some that were HUGE - 2 to 3 inch diameter and 10 to 12 inches tall IIRC.

Tubes for large radio transmitters. Some ham operators like my buddy still use them. If the tubes were still good, you threw away some real money.
