The RCA 1644 tube is a 12L8. Not a 12L6. The two sections share a common cathode.
They were probably designed to be used in the output stage of radio receivers.

thanks frank ill just add em to the rest of em. maybe down the road i can use em.

only cost me $11;)

yeah, it's a 12L8.

shared cathode and screen, so ideal for PP.


but, unfortunately it is rated only 2,5w Pa, each section.. so flea power, unless you use your whole set in PPP ;)
