Danny, What I meant was any measurable resistance (less than infinity), across the variable cap and the associated padders (nos 4 or 9) could kill the grid voltage developed by the secondary of the coil. Might have to disconnect the coil to check this. Another possible problem might be poor pin/socket contact. If plate and cathode voltages are good, don't see why there is no grid voltage. Might have to wait on the experts to chime in.
