One of the two resistors to the base of the U801
in this receiver short circuited and as a result this
valve burned out. I renewed both the valve and
the resistors but now, although all the valves light and there is no obvious fault, the set is completely dead; no sound, no raster and no e.h.t. I conclude
that there is no h.t. but I cannot trace a fuse in the
h.t. line.-H. H. Williamson (Formby, Liverpool).
There is no separate h.t. fuse on this receiver and we, suggest you check around the main electrolytic capacitors and especially the h.t. smoothing
choke next to them, below chassis.
