crusty old valves

[turing]

picked up 2 ancient radios at a rummage sale this morning, and they're crammed full of weird and wonderful valves. i was hoping someone might be able to tell me what i can use them in....................

in the first one, a german set, there's an ec92, ech81, ef93, eabc80, ez80, el84, and em85. haven't cleaneed them all up yet, but some are made by mullard, and some by lorenz.
in the other set, uch42, uf41, ubc41, ul41, uy41, all seem to be mullard.

now i'm only just working on my first valve project.....the shake tube. but if anyone knows what use these could be put to, or what modern equivalent they could be swappeed for, i'd be very grateful

The EZ80 is a rectifier and the EL84 is a power amp tube. The rest I have no clue on.

first letter

E = 6.3V heater
U = series heater string iirc, have weird voltages like 19V

second letter

C= triode
F = small signal pentode
L = power pentode
H = heptode?
A = small signal diode
Z= rectifier
B = dual small signal diode

third repeat

ex. ECH = 6.3V heater, triode, heptode

numbers that start w/4 = Rimlock base ex. UF41

looks like lots of radio tubes. As far as I can tell only the EZ80(Russia?) and EL84 are the only ones you'll find in modern production.

no problem! I don't know if I'd want to use that as a reference though, lol. A complete reference should be in the Groove Tubes book (by Per somebody?) and somewhere else on the 'net too, IIRC. Also, keep in mind some tubes don't follow the convention (KT66 I think was one example given).
