Dave. Top three are numbered, D8010L Bottom two are, A69108 Is this pic any help? David D |

John. I appreciate you trying to educate me..... But! Where do I get low voltage AC from? :scratch: The control board instructions are beyond me........ ::) Seriously out of my depth now! :bang: David D |

Nearly same as mine, I have the bits ... dunno about the technology ??? @John When the one on my WM16 was visited by blast, fire, pestilence and a general all-over immolation. The varistor, X-cap and the diodes were all intact. They're still in there. Both SCR's were s/cct, hence the aggro. Just replaced those .. @ Dave SD Low voltage AC is the forte of a Variac ... Variable Transformer ... I think that A69108 number was non-findable, maybe it's an in-house P/N ?? Dave BC |

Hi Dave , I assume you will be working with Dave BC the safest way is with a step down transformer ,to limit the current to about 1/2 to 1A to make the voltage between segments large enough to measure , about 0.2V and not two bulbs connected to the mains as I did as an apprentice at Pilkinton's , about 1974 ( before H&S) If the board is the problem we will need the circuit from Andyf John PS Dave bc just seen your post , yes they could be in house numbers any component in the controlled bridge rectifier that goes short circuit will take the other one with it , sooner or later even if only one looks faulty I'd change both |

Hi John I have I-limited DC anyway ... Trouble with Variacs, being Auto, never quite sure which may be the hot end. No doubt would be fairly briskly enlightened with fingers poked in eh ?? Dave BC |
