Default Re: DC Mains on Pre-War TV's

Thanks everybody- fascinating debate. Like David, I don't think an all electronic converter would have been an option for a pre-war tv due to the high loads. It sounds like the majority would have gone for a rotary converter as any standard set would work on these. The downside I guess would be a place to put one where the noise is not too intrusive
My Philips converter manual mentions 'additional parts'. These are most Cs and Is presumably to suppress interference from the vibrator. But one item also mentioned is a motor from the Garrard RC5 or Garrard U5. Presumably this applied to Philips TV radiograms. But why would you need to change them? I can only think that the frequency of this converter was different to standard 50 hz AC . It's frustrating that it doesn't need give details. Let me know if anyone is interested and I'll scan it and post it
