Valveholder Chart
| The chart above shows the pin numbering for common valveholders such as B7G,B9A and OCTAL etc. Together with some not so common types. It will open in a new window for printing. |
DK DF DAF and DL 91,92,94 and 96 Series Valve Data for Portable Radios
All pictures will open in a new window (if you have a pop up blocker please turn it off).
Equivalent Types.
91/92/94 Series Valves
Pinout is exactly the same as the 96 series. The heater current is higher at 50ma as are some of the valve parameters.
