Hittade ett EC 85 rör på insidan också. Vad är vad i den?1st letter heater indication
0 tubes without filament
A 4 V AC parallel connection
B 180 mA DC
C 200 mA AC/DC series or parallel connection
D <= 1.4 V DC dry-battery, parallel connection
E 6.3 V AC or carbattery, parallel connection
F 13 V carbattery
G 5V AC parallel connection
H early: 4V DC battery. later: 150mA AC/DC series connection
I 20V AC/DC parallel connection
K 2 V battery
O 150 mA AC/DC series connection
P 300 mA AC/DC series connection
U 100 mA AC/DC series connection
V 50mA AC/DC series connection
X 600 mA AC/DC series connection
Y 450 mA AC/DC series connection
2nd+next letters tube systems
A single detection diode
B double detection diode
C small-signal triode
D power triode
E small-signal tetrode (or 2nd emmission tube EE1)
F small-signal pentode
H hexode or heptode
K octode
L power pentode or power tetrode
M indicator tube
N thyratron
Q enneode
W single gasfilled rectifier diode
X double gasfilled rectifier diode
Y single vacuum rectifier diode
Z double vacuum rectifier diode
digits socket & order
x P (some are V) (except U-series (e.g.UBL1), those are octal)
1x Y8A
2x W8A, Loctal (except D-series (e.g. DL21), those are octal)
3x K8A, A08, octal
4x A8A, B8A, Rimlock
5x T9A, B9G, Enne-al and C2R and some special bases
6x Subminiature
7x Subminor8p
8x, 18x, 8xx B9A, noval
9x, 19x, 9xx B7G, miniature-7p (Exception: The ECC99 is a poorly chosen tube type number, as it comes with a noval base.)
2xx, 2xxx decal
5xx B9D, magnoval
Så EC 85 betyder en triod med 6,3V glöd och B9A novalsockel, 5an betyder rörtyp 5 ungefär.
Följaktligen betyder till exempel ECC 83 att det är en dubbeltriod
Osv
Resten får du tyda själv (wikipedia är bra att ha om man söker)
