6384s are wonderful things - sort of like a 6AR6, but built like a tank.
Best to send them away for safe disposal, as with any of the other "Red Bank" valves you may find 😀

Thanks choky, thanks SY. thanks to all for the response , i got the data for these tubes,i hope to build something about these Gianis.🙂

Re: tubes
do not build anything with this crappy tubes ;
send them to me ( you pay just little postage from Greece to Serbia ) and I'll smash 'em for ya

Anyone got a schematic for Bendix 6889's?
Very similar to the 6384's.....
Can be run as Push Pull or single ended as I have a Quad

There are some 6889's on Ebay right now
and I've just got a Quad of these, similarly awesome construction and specification; gotta build an Amp around these....

Hey Gianis, aren't they radioactive as used in nuclear weapons ? 
SEnd me them so that i can say with my GeigerMUller counter 😉 pay attention

Most 6L6 circuits will work fine with the 6AR6 and 6384 (within the maximum plate dissipation ratings). Some bias adjustment may be needed. Keep in mind that these tubes have a different pinout than the 6L6.
The odd pinout solves the arc over problem that happens with any of the common audio tubes. A 6L6GC or any of the others are prone to an arc from pin 3 (plate) to pin 2 (a heater pin that is often grounded) when operated at high plate voltages and abused, like a guitar amp. This is why the 6AR6 has a higher plate voltage rating than the 6L6GC and the 6384 is even higher at 750 volts.
I have some of both tubes. I wired the 6384's into a 6L6GC amp several years ago, but that amp didn't take advantage of those tubes. It was a wimpy 30 WPC amp. Further experimentation will occur in the next few months.
