Here is the Ken-Rad implementation of the 6L7G. The 6L7G was designed to ensure maximum isolation between oscillator and signal, and to provide a mixer which is efficient.
The attached PDF applications note gives many uses other than as an oscillator/mixer. It can be used as an audio amplifier and/or as a gain controlled audio amplifier.
Thanks to M Asjes for sending the image.
The classic envelope is  mm in diameter and, excluding the IO base pins, is  mm tall.
References: Data-sheet, 1043 & 3002. Type 6L7G was first introduced in 1936.
