I had a converter fitted about August, and we had ITV and BBC. Now I can only get ITV; when
the aerial lead was fitted direct to the set, BBC
could not be got, as all the valves light up. Could
you. inform nie where the trouble is ?-F. G.
You do not say what type of converter was fitted. We must therefore assume a Bush T184
tuner unit is referred to. In this case, check the
two EF91 (or EF80) valves behind the tuner
unit, the supplies to them (resistors, etc.), and
the setting of the BBC tuner just to the right of
BBC aerial input. The core of this adjustment
may have become displaced. Check EF91 valves on left side and associated components before
taking any other action.
