I glad it's caused a discussion. I got a schematic and it shows lamp voltage at 7volt .3amp. I put a mm on the lamp socket,(no valves or lamps) mains is 243v, mm reads 7.6v. I found a couple of 6.5v lamps put the valves back and the mm settled down to 7v. I then connected my lamp limiter with 100w bulb and the mm reads 6v. (lamp runs dark). I'm favoring a beefy resistor in line with the pos' mains, I can knock up a heatsink for it, thing is what value and wattage?, I'm lost in the calculations. The radio is rated at 50w. I would like a cheap solution if possible. I've a few old radio's waiting work and I'm sure to come across it again. This Loewe Opta Toccata 1745w is a beaut' and needs lots of work, after 60/70 years the plastics are just crumbling in my hands, no solution for that though!.
