Mullard Valve Pin-out Slide Rule
This little gadget (from the early 1960s?
- It has the EF183 and EF184) gives the pin functions for
many Mullard valves. One side has 7 and 8 pin valves
including many older octal ones - ECC33-4-5, EL34, GZ34
etc. The other side has all the commoner Noval ones including
ECC83, EL84 etc. You slide the green cursor until the valve
type appears in the bottom window, then the pin functions
are visible in the other windows.
