VFE SWITCHING BOARD - No clean bypass signal?
« on: July 12, 2023, 01:35:38 AM »
I built the Old School (opto tremolo) with the VFE Switching Board.

The effect worked, LED flashing with speed, all pots and switches worked.
but somehow there's
No clean bypass signal

Is there a way to verify the Relay?
Does anyone have voltages for the other ICs?

Thanks!

*UPDATE*
It was the LP2950, there are 3.3v or 5v options, I had the 3.3.
once I replaced it with the 5v the Relay started working as expected and the switch works.
Pretty small detail that is difficult to catch in the build docs. So hopefully this helps someone.

I did the same thing, wasn't aware there were different voltages available.

How loud is too loud?  What?

I missed the original post, but caught this one today. 

I've had a VFE build in my de-bug pile for a year now scratching my head over a similar problem.  I just checked my parts stash and I have both the 3V and 5V regulators.  Really appreciate the post, this made my day.  8)
