[Hallicrafters] S-76 tube shields?

[Porkchop]

Hello all-
I was wondering if anyone can tell me the proper location of the
tube shields on the small envelope (7 pin) tubes? My S-76 does not have enough
shields for every tube, but I'm not sure if they all need one.
I can tell from the manual photograph the obvious locations that
have them, but two of the tubes are obscured by other components.
The tubes I can't see in the manual photograph are V7 (6AL5) & V4
(6BA6), do these have shields? Maybe someone who owns another S-76 could tell me?
Thank you.
Glenn
