Title: 18k substitute
Post by: trickpony on October 10, 2012, 08:26:51 PM
I am builting a double flush and don't have an 18k resistor for r14. Can I sub a 15k or 22k and if so what would this change? I could also put a 10k and 8.2k in series I suppose...ugly though.

thanks,
Ben

R14 is part of the gain stage for the LFO. if you use a 15K for R14 and swap R15 for 3.9k, you can keep (roughly) the same gain overall.

otherwise, if you want a slightly deeper trem effect, use 22k. slightly shallower: 15k

Of course, if you have a 3.3K or 3.9K resistor, you can make a tepee with your 15K and you're all set!
