Re: VU BUFFER & PEAK LED KIT BUILD THREAD

Joe, Thanks for your reply re the 1N4001, etc diodes for use in the peak LED circuit. In breadboarding the VU buffer, I noticed that, if the gain adjust pot is near its highest gain position, the 1/2V voltage divider & cap (R12= R14=47K, C5=100uf) fails to ramp up all the way to 1/2 V. E.g., for a 1...

Re: VU BUFFER & PEAK LED KIT BUILD THREAD

Hi Joe,

Why do you mention using a high speed switching diode (1N914, etc) for the peak LED circuit on your VU meter buffer board? Wouldn't a "garden variety" 1N4001 silicon diode work fine in that application?
Thanks.
