Re: Marconiphone 855 Silent on 49m
A most odd fault. One thing worth checking is the capacitor that decouples the oscillator HT-feed resistor to earth; I have in the past seen cases where this capacitor misbehaves and reduces the osc. feedback level which can cause some very bizarre effects like apparent 'gain' varying as you tune across a band, or in one case the oscillator would work if you switched the receiver on when it was tuned to the HF end and would then continue to work as you tuned it LF, but the oscillator would not start if you switched on with the receiver already tuned to the LF end.
That one had me foxed for a day!
