    I would like to be so lucky as to find one of those. I have plenty of testers, but the one above is a conversation piece.

    yeah man, I've got a few of those. What specifically would you use the 50c5's in? 50V is a hell of a filament voltage...

    Very cool! Must be something about being in the living room thing with these things. Can you take a close up pic of your board? Some of the print on mine has faded and I'd be curious to see what it should say. Thanks!

    I've got a Garnet 5P that uses the 50C5. But I have a sleeve.
    I'll take any 7C5s (locktal 6V6) :)

    those are used in ‘American five’ circuits in radios and the so-called widow maker amps..and the versions of the widow makers that have an isolation transformer. These amps run a 35xy rectifier and a 12a-7 preamp/driver. Add up the heater filaments and you get close to the wall voltage, right?

    The 2.3 Ford engine was used in a lot of inboard/outdrive boats too.

    Wasn't there a version of this engine with two spark plugs per cylinder?

    The dual sparkplug version was used in 1990s Ford Ranger pickups. Not bad for an engine that was designed in the very early '70s.

    There is also a propane powered version used in power ladders / power scaffolds. That's the popular "boom truck" device mounted on an offroad chassis.

    Any 32ET5's? A crazy like a fox sort of guy in another forum took a pair of these series string tubes that are rated for a paltry 1.2W in TV service with 110V, upped the voltage and ran them in Class AB2 resulting in 30W.

    Forgot to add,

    "The 50C5 will make the same 30 watts on 340 volts"
