The top caps will produce some hi power and in the 60's and 70's they would use the innards of these tube type tv's and make a illegal cb radio amplifier, there was big demand for them. Even today some of those older amps are still running so they need extra tubes, plus you have the ole tv restorers trying to rebuild the tv's. They just don't make some of those tubes anymore, Russia is making some but I don't know if the quality is there or not. Also some of the small tubes were used in early car radio's.
