Re: Oh No! Not another howler.
I suspect that it is not the audio taking off on its own as it is stable at all volume settings when in "gram"
If shunting stray IF to ground fails I may have to think about a few mods.
True about pared to the bone, only 4 valves, common chassis punching with other models, lots of unused holes, and the cabinet, scale pan, speaker/output transformer and knobs are of course common to many models produced at this time.
Even the valve line up is an economic measure, three B8A and one B9A.
The mains transformer is also thinner in the core than some others.
