Hello all,
I recently acquired a mid production model 90. Single ended 47 output. Anyhow, my question is....Where there production variations on how the shielding was done on the 90 chassis?
For instance on my chassis, the large 3 section shield is in place. One 27 tube near the back center of the chassis has the classic round Philco shield. However there is a plate separating the 27 and 80 near the transformer from the 47 and 27 near the mershon caps instead of another single circular shield (it looks as if the plate is original).
Thanks for your input!
