I need help with repairing a dimmer circuit on an old microscope. The bulb is 30 watts and it lights but no dimmer. I apologize if the photos are no good. It is an old style circuit if you can see and I believe the burst grey cannister triac is the problem. Can anyone help with what/where I can get a replacement? It is marked with a line of japanese script and "ES-0001".
Or could I just replace it with a modern say 200v, 6 A triac like SC141B?
Or should I just scrap the whole thing and retrofit a standard wall switch dimmer?
Thanks for any help
