Pune poze, ca dupa cod nu par rusesti iar descrierea e mult prea generala

Eu cred ca este un tub folosit ca ''fotomultiplicator''...Justificare: lipseste depunerea de bariu si exista o dispunerea simetrica a electrozilor...

Probabil sint "decatroane"="numaratoare decadice", ceva ca aici:

sau

http://oldradio.onego.ru/new_tubes.htm (vezi А106, А101, ОГ3, ОГ7)

 

Modelul tau e mai nou probabil decit cataloagele mele, care sint de prin 1960-1970.

 

Fotomultiplicatoarele sint mai lungi si au un fel de lentila in virf, asa ca nu prea cred sa fie.

Cand l-am ajutat pe Amper cu fotografia, mi-am dat si eu cu parerea ca ar fi numarator decadic. Pe vremuri erau niste aparate cu care se efectuau diverse masuratori in laboratoarele de fizica ale facultatilor, etc.

Daca grilele au7n forma circulara si sunt pararelele intre ele sigur e decatron.

Si uite cum ai rezolvat problema celor 28 de tranzistori driveri pentru tuburile NIXIE! Eu voi ramane la ideea de a utiliza tranzistori.
