Hi
I'm in the process of repairing a G11 for a forum member - the set is in a Dynatron period cabinet. In the base of the cabinet was an ice-cream tub (see photo). What? Two wires went from it to the fuse board soldered to two 5A fuses, the originals having been removed, and the other two wires went to the IF strip. What's in the box? An AC/DC universal adaptor, a rheostat (as I'm sure the installer put it) and a fuse.
So what on earth? Further investigation suggests that the set had no sound. Our repairer finds the audio fuse on the line panel open and its feed rectifier shorted. However he replaces said diode with a normal RS rectifier, but, as it's not a fast-recovery part, finds only a few volts available to the audio stage. Hence this arrangement to power the audio stage!
I don't know how long the arrangement worked for, if at all. I won't make any comment on fire hazards and safety - but it certainly represents an old-school approach to solving a (for the time) new technology fault.
