I'm in the process of laying out a circuit board for the Buchla Lowpass
Gate. The original module used Vactec 2C3 Vactrols. According to the
chart in the Newark catalog the stats for them are: Max On-Ohms Light
Adapt - 2000; Max Decay to 100K 35ms
If I understand this correctly, the first is the maximum resistance one
of these devices will offer. The second seems to be response time.
The reason I'm posting about this is because I have a stash of Vactec
5C4s and 5C4/2s, which have different ratings. The max on ohms for these
are 200 and 500 respectively and Decay is 1500ms for both.
My guess is that I could compensate for the resistance differences by
changing other resistances in the circuit, but I wonder if the lag would
be too great.
Any feedback? Sorry if this is something really obvious, I'm just not
that familiar with optoelectronics.
