Tubes 5963

I have picked up 25 pieces of 5963 tubes
I know only that they are double triodes but can't find more info on them
What double triode that is 12AT7,12AX7, 12AU7,6DJ8?
Please if you know anything about these let me know
Thanks

The reason I ask is that I'm new to tubes and picked up a bunch of matched HP Toshiba 5963 tubes for my tube amp. I currently have some Electro Harmonic 12AU7 re-issue tubes and a Baldwin tube in the amp right now. IÂm hoping these 5963Âs sound good. Thanks
