Fender Opto Coupler

[Shawnobi]

I need an Optocoupler for the tremolo in my Bandmaster based build. Figure I just make one myself rather than get one posted from the US.
Does anyone have the specs on what the photocell & neon bulb should be?

Thanks.

This combination has worked well for me

I bent the leads of the LDR so that it can be fitted to the side of the neon. It might work end-on but I never tried.

That's helpful information, and believe it or not, it's pretty hard to find these specs by searching online. I ended up rolling my own, using a generic neon bulb and a photocell that ranged from 5M (dark) to 2k (light). I guess got lucky because it worked.

I think this information needs to be in a FAQ somewhere...
