47 pentode
Sory Allan try with this url
http://frank.pocnet.net/sheets
And put in the case search (47),after you can download the pdf files and view some graphics.
I just scan two schematic of 47 (single-end and push-pull),
both of the 30's.
If you are interested, tell me
Good luck

Hi allan ,i remember now where i see something about the 47
and the nearly same tube 42 except for the heater (6.3 volts,direct heating)
After all you can find in the last url the pdf file of the 42 from
General electric but it's in french .
they talk about the replacement from the 47 by a 42
and tell about uses in triode with 42 in interstage,in triode
If you have 1 of those you can see is the same construction of valve,strange now!
Pearhaps with the value of the 42,you can find solution to your project.
I try to compress the schematics and send to you
Good luck
