Couldn't agree more, I guess its possible but in most electrostatic deflection sets these are usually in the region of 0.05uF with 2 to 4Meg def plate resistors to get an adequate low frequency response for linear vertical deflection, so I wonder if it is a mis-print on the schematic, might not be , but worth checking the actual value of the caps in the set. (Anywhere from 0.001 to 0.005uF is fine for coupling to the H def plates).
Ignore my remark about the spring clip in post 23, this set has a separate feedback winding on the EHT transformer. Also there is a tuning control in parallel with the 750pF tuning capacitor on the EHT transformer, this will affect the EHT too.
