Philco 90
#9

...ummm...actually...

There is no shield (divider) between the group of four tubes (one 27, two 45s, one 80) in the early version of the 90.

Jeff has an earlier version of the "mid" production 90 (1-47). The earlier production models of the 1-47 model 90 have a tubular shield surrounding one of the 27 tubes; later production of the 1-47 chassis has a flat metal plate between two of the four tubes. The 2-47 (late) version also has the flat metal plate.
