SV: SV: [AMPS] ID small amp tube+

[sm5ki]

This double tetrode was very common in Europe in the old days and is also
called QQE 06/40 ( Philips ) and QQV 06/40 ( Mullard ). It is built
symmetrical like a 6J6 with the cathode in the middle and the grids and
anodes on both sides. It has built-in neutralisation and has been used as a
linear tube on short-wave with both systems in paralell and external
neutralisation. Output was in AB1 abt 50 watts. Another version was the YL
1060 that had a higher anode dissipation and YL 1070/ YL 1071 that had no
internal neutralisation and was used for SSB with the sections in paralell
on short wave delivering 158 watts SSB in class AB1. There was several
smaller versions like for example the QQE 03/12 ( 6360 ) etc. The socket
used is the same as for the 8877.

This tube was used very much in FM base stations and by radio hams up to 500
MHz. Nowadays
very cheap on flee markets and one of the most used transmitting tubes in
the world.
