[ARC5] 12 V Power pentode.

[Howard Holden]

So, inquiring minds want to know, Ken, and a few have asked for hints - 
what's the power pentode going to be used for/in?  And why not a beam tube?

I had thought of the 837, Howard, but that won't fit the available space.

It is a very neat tube, BTW.

The 802 is another good one. Same thing there though: won't fit the 
available space.

Dang... :-(
