EKCO TMB 272

< Back

This is a mains/battery set. The h.t. on mains
reads 200V, while on battery it registers as low as 165V with a corresponding drop in performance. The battery consumption at 12.3V is also less than
specified. I have substituted the smoothing capacitor and
checked the vibrator pins. I have substituted a
Mallory 629 vibrator for the Plessey type 1214 which was the original, but have not improved the h.t.- J. C. Boylan (West Monkseaton, Northumberland). This trouble is caused by a faulty pair of metal
h.t. rectifiers which are sandwiched between the
back of the chassis and the back of the set.
