Summary

The 6BV7 was designed by AWV to combine the functions of detector and output valve in four valve radios that did not have an audio amplifier between the detector and the output stage.

Manufacturer: Amalgamated Wireless Valve Company (AWV), Sydney, Australia.

There was nothing like it on the American market at the time and the nearest European equivalents were the EBL21 and EBL31, neither of which was ever produced in a 9 pin miniature version.
6.3 V indirectly heated cathode.
