Does anyone  have the pinouts for the RCA 807 tubes? Or where a silly person
like me can  find out this kind of information? Are there any interesting
VTTC  schematics that use this vacuum tube? What are these big huge Macroni
810's  all about? Any tube heads out  there?

Hi Miles,
 
>From the RCA TT-5 Manual "Transmitting Tubes"
 
The 807 Beam power tube pinouts:
 
1& 5 Heater
2  Grid 2
3  Grid 1
4 Grid 3 & cathode
Cap  Plate
 
Max Plate voltage 750 Volts
Max Power out 60 Watts
 
The 810 is a power triode good for 750 Watts @ 2500 volts ICAS class  C
 
    If you like real books,The TT-5 manual occasionally  shows up on eBay, or 
reprints are available from Antique Electronic Supply Co.  Tempe, AZ. (<$20) 
The RCA manual TT-3 also comes up used sometimes, is  older, (ca 1938) and 
does not have some of the  tubes in the TT-5.  Both of these contain a wealth of 
info on tube theory and design as well as  complete schematics for a number of 
devices.
    While I haven't had to design anything with tubes  since 1968, I can try 
to remember a few things. ;^))
 
Hope this helps,
 
Matt D.
