When the 6A7is returned to the socket it does screen voltage. The 6SB7 receives it's screen voltage from the LO plate supply. It will have HV on it it's just getting it from source. The 6A8 needs two connections to the HV (G2 and G3/5) The 6SB7 only needs one on G2 and G4 which are internally connect.
