  1. I can buy CdS photoresistors no problem, I just don't know which type to use. By "bright light resistance as low as possible" you mean photoresistance? Right now I am looking at photoresistors with photo resistance values ranges in kiloohms: 2~6, 5-10, 8-20, 16-50, 30-90 and 45-140 Kohms. Then there is the minimum dark resistance, it is given in megaohms. At which value should I be looking?
  2. Hello, do you remember the replacement photoresistor specs? Or where can I get one? Is there a way how to identify a camera photoresistor? It's a pity that we don't have service manuals for cameras, similar like there are for hi-fi, radios and similar equipment. I have two Electro 35 FC's that I would like to bring back to life. I have replaced the faulty electrolytic capacitor in one already, it didn't help. The photoresistor is in a metal can, it has "A4H" stamped on its side. Many thanks for any help.
