vactrol question.

Hi guys, just have a question about a roll your own vactrol....i know you need a ldr and an led....could a person use a HERMETIC SILICON PHOTOTRANSISTOR instead of the ldr...it says on the datasheet:
Devices can be used as a photodiode by wiring the collector and base leads....or will it not work.

probably not, but post the datasheet?

here's the link to the datasheet : http://www.datasheetcatalog.org/datasheet/fairchild/L14G2.pdf

If i can't use it for that....i have two of em, will they work in a boost circuit?

[stecykmi]

I would say that they are not drop-in replacements for the resistive-type circuits we typically make. you could make some type of LFO but it would have to be custom designed.

as for a boost, i don't these things aren't suitable for audio! they respond far too slowly.

oh okay, no big deal, i didn't buy em anyways, they were given to me....just thought instead of goin in the garbage i could make use of em.....thanks.
