The M8248 is a special quality UHF triode for use as a grounded grid amplifier. The construction is interesting and difficult to determine. It appears to be highly screened.
The thin glass tube envelope is 17 mm in diameter, and excluding the B7G base pins, is 42 mm tall.
Reference: Datasheet. Type M8248 was first introduced in 1962.
