The first letter indicates the heater supply.
A: 4V
B: 180mA, various voltages
C: 200mA, various voltages
D: 1.4V
E: 6.3V
F: 12.6V
G: Various voltages
K: 2V
L: 450mA, various voltages
P: 300mA, various voltages
U: 100mA, various voltages
V: 50mA, various voltages
Y: 450mA, various voltages
The types where a current is stated, are series connected and
connected directly to the 120V or 220V mains supply. There where used for
low-cost radios and TV's.
The second letter(s) indicate the tube type.
A: signal diode
B: double signal diode
C: low-power triode
D: power triode
E: low-power tetrode
F: low-power pentode
H: hexode or heptode
K: octode or heptode
L: power tetrode or pentode
M: indicator tube
Y: half-wave rectifier
Z: full-wave rectifier
The first figure indicates the socket type.
1: various types
2: decal (miniature 10-pin)
3: octal 8-pin
4: rimlock 8-pin
5: magnoval 9-pin
6: enne-al 9-pin
8: noval (miniature 9-pin)
9: miniature 7-pin
The last figure(s) are the tube type number.
There are (of couse) some exceptions to the rules. Some tubes have a
"1" in front of the number, ECC189 for instance. It is still the 8
that indicates the socket type.
I hope this information is helpful and hopefully complete. The
information is from the Philips Pocketbook 1968.
