Re: Earliest BBC2 Sets?
Pye 11U stock faults:
1 Mains dropper.
2 Poor BBC2 sound due to L28 unwinding and slipping down former. Remove can, dab winding with
Bostic and retune'
3 Preset contrast control [270K] burning up badly causing damage to wiring. Replace with
680K.
4 Feed through ceramic feeding heater voltage to UHF tuner going S/C robbing valves
in lower end of heater chain.
5 Frame cramp. O/C bias cap.
6 Knobs broken off rear controls.
7 High level tapped contrast control going O/C. Very common.
8 Tangled UHF drive cord. [DON'T GO THERE!]
9 Fizzing EHT rectifier valve base due to dampness usually caused by nicotine and the
dreaded paraffin heaters.
10 Exploded mains filter capacitor.
11 Lack of height due to series resistor from boost rail going high, 1.2M I think.
That is all I can remember. One of the more reliable dual standard receivers.
