E810F/7788 Pinout name/number?
I'm trying to figure out if there is a designated name for it's pinout?
I know it's quite similar to a few other pinouts an using the correct pins it's interchangeable, but I find no other tubes in that realm with both pin 6 and pin 9 being G2, my reason for an inquire is I'm cobbling up all the pinouts that when g2 and g3 are strapped to the plate and pin 1 is used for cathode they become pin "compatible", an I'm listing all the pinouts in excel spreadsheet, but I find no designator for the E810F/7788? Are there other tubes with the EXACT same pinout as that E810F/7788, as I find none yet? Thanks, Keg |

The D3A is very similar, but missing the G2 grid connection to pin 6.. (Notated as an internal connection, but i have never checked to see what it is connected to..) You could just ignore pin 6...

Yes here are 5 of the pinouts, (referenced to 6EJ7, 9AQ) that when strapping
pin 8 and pin 9 (g2 and g3), to pin 7 (plate), use pin 2 (grid), pin 1 (cathode) they become "compatible" triode strapped pinouts. Compare that to E810F/7788, it will work as well, what I was looking for were there any tubes with that same pinout as an E180F/7788 I may be missing, so I was trying to find out if there was a designation for it's pinout so I may look.  Yep D3A an such are on my list. as are 6J52 an 6J9.  (rig the heaters 12BY7, 12GN7, 12HL7 could as well) I just haven't seen a designation for the E810F pinout?
