Someone said double pentode. Another said the 5670 is a drop in for a 6n6. The 5670 is a twin triode though.

Off another site:
"6N6 (chinese), 6N6P (russian). This tube has NO known direct replacement: the best replacement is another 6N6 - 6N6P. However if you are experienced, and with the proper tools, it could be replaced (given socket rewiring and maybe some circuit tweaks) with 5687, 12BH7, ECC99 or E182CC. This last tube seems to be the closest equivalent."

The Chinese 6N3 is a double triode similar to but not the same as, the Russian 6N3P. It has the same pin out.

Wait a minute, this is not a 6n6, this is a 6n3, they are very different.

5670 is in fact a replacement for the 6n3 as is the WE396.

I didn't mean to start a war about what type of tube it is and what kind of replacement you can use...I just wanted some input on this, that's all...

I'm still wondering if I could just bypass the step up circuit and give the tube 110v from a 12v inverter?

Thanks,
Nicholas G.

You could use an external B+ supply or, perhaps use the attached voltage multiplier to replace the one on the circuitboard.

Good to know that the 5670 has the same pinout.
Thanks.

The 5670 is a nice little tube, I have A GE one which I enjoy a lot in my modded MHZS player.
