| Description |
| |
Although the 5 pin socket looks like a 5 pin UY, the tube can be plugged into a standard octal socket.
The "octal" pins are (3-4-5-6-8).
Keying is done by an external lug identical to the European PTT G7K base (E2C...) instead of the usual octal spigot, on a PTT211 picture we can see a white line added at this lug (collector info).
