[AMPS] RCA/MOTOROLA 4657 TUBE

[sm5ki]

I got this 4657 tube together with some kind of surplus cavity it seems made
by Motorola around 1991? It looks like my 8072s but what is it? There was
also some kind of strange screen grid finger stock  ( condenser ? ). It has
been used in some broadcast gear made by Motorola?
