Summary

6SH7 type pentode, 6.3 volt indirectly heated cathode at 300 mA., manufactured by Ken-Rad, Owensboro, KY, USA, 1938. Sharp cut-off RF pentode used for RF and IF amplification. Its relatively high mutual conductance made it useful in wide-band amplifiers.

The data code (B8) indicates that the manufacturing year was 1938 meaning that the valve must have been in store for some time before it was accepted in 1942.
