Greetings everyone,
Does anyone have any data on the 12JZ8's?

Thanks,
Ray

There is a 6/13JZ8:

something of a mini version of the 6LU8:

Thank you, don't I feel stupid for not thinking of other voltages.....

Looks like that 6JZ8 has a nice constant Mu 20 triode in it. The 6LU8 triode is higher Mu at 58 and fairly constant, and the 6LU8 has got better voltage and wattage ratings. Maybe the 6JZ8 for driver duty. The 6LU8 gets used for spud amps frequently.

I used 24JZ8 as a driver in an amp with MOSFET source follower output. Also, I used in similar application 8AL9. Pentodes triode strapped.
