966A rectifier

[abj1]

Hi All,
Another question about an obscure valve. Anyone have filament voltage/current info on the 966A rectifer (not 866A)? Other info would be much appreciated also.

TIA,
Andrew.

I suspect these tubes are this brands versions of the 866A and 838, but am not certain. 838 is a graphite plate triode optimised for for 0 bias class B audio power amplifier and modulator service. Somewhat similar to 811A/572B.
