Recap Question
#4

Derek

1. No.

The 1 pF is, most likely, a wire "gimmick" which is run between the oscillator stator terminal and RF stator terminal of the tuning condenser, connected only at one end. The end that is not soldered is probably wrapped around the other terminal but not electrically connected. This is a "gimmick" - a twist of wire giving a very small, but necessary, capacity in the circuit.

2. A "twin bakelite block" is merely a bakelite block containing two capacitors of the same value.

3. Part (67) contains two 8 uF electrolytics in the same can. It may be replaced by two separate 10 uF, 450V electrolytics.
