There is a good raster but neither sound nor vision. I have changed the tuner unit valves with- out improvement. I have also tried alternative
aerials but without any results.-W. Wilkinson
(Belfast 13).
It would appear that there is a fault in one of the
two if, stages common to both sound and vision, V3 and V4. Check the h.t. supplies to these stages, checking at pins 7 and 8 in each case, and replacing
any burnt -out resistors and shorted 0.001µF
capacitors.
