Valve Gallery - Rare And Unusual Valves (3)

Valves: EA52, L2512, 2700U, CV410 (K3A).

A couple of wire enders next.  Above is a Miniwatt EA52.  A diode of some sort, with gold plated connections.  Height of 44mm excluding wire connections.  L2512/450kv.  4 wire leadouts.  Glass body is 47mm.  Might be limited production as hand painted legend.  Must be some kind of valve as it was amongst other valves and nothing else.  Any info email me at contact here

Shown above is a Mullard 2700U. Four digit ident numbers from Mullard often indicated special quality.  Wire ended connections, of 24mm height. Holland made. Lots of top caps, but no pins!  Above is CV410.  Apparently a cold cathode gas triode.  Commercial equivalent of K3A from Ferranti, but I've never seen another like it.
