Yes David the Hopt tuner used in the PYE 11U. Not a lot of gain and if you were careless in replacing the PC86 and PC88 valves, the ceramic capacitors soldered to the base pins would crack. Also had problems with the lead through capacitors to the heater pins breaking down to the tuner housing robbing the final valves and if I remember the CRT of heater current. 'Oh don't bother with BBC2. We never watch it anyway' and that was from customers you probably think would. John.
