This site limits the size of pictures you can post.

However, comparing the circuit in Aford's post to the one in the Electro 35 manual, I can't see any difference and I can't see anything that will automatically switch the shutter speed to 1/30th. The circuit does show the switch which allows manual selection of Flash or Bulb though. So maybe it's not a GX circuit at all. (Actually, looking closely, it looks like it says GS at the top not GX).

You can download the Electro 35 manual from http://www.scribd.com/doc/19302555/Yashica-Electro-35-Service-Manual. If you look at the circuit, C1 is the timing capacitor which is charged either through the CDS cell and parallel resistor, or through the fixed resistor R3. Not sure what the purpose of the Bulb Switch is though.

I'm not that familiar with the GX so can't help beyond that.
