Thanks, I'll order a couple when Small Bear opens back up.

Thanks.

With 3007 removed, both are 7.4v
With 3101 removed, both are 9.4v

Is that sounding like a problem with the 3101?

I'm not sure how I would tell.  They are both around 7V with the chips in place.

Okay, dug out my bench.  I removed D4, and the voltages didn't change.   Pin 1 on the sockets is 9.4 for each chip. 

Not sure where I got the 3101 from, I thought Smallbear, but very likely I'm mis- remembering that...

Thanks!  It'll be a week or so before I can try those ideas.  Just had my oil tank replaced, so half my basement is in my work area...  They tore up my floor paint dragging the tanks around, so need to wait for the touchups to dry before unburying my bench.

Hello,

  I'm trying to figure out the Pork Barrel and not having much luck.  I've reflowed everything.  I get a strong clean signal with the effect on or off.  Attached are my pics, and here are the voltages I'm getting

Thank you so much!!!  It was a bad SK30 transistor.

Hello,

  I'm going through the pedals I can't figure out and have hit the Agua Net.  I can't really understand the schematic (for example there are a bunch of circles with the word "pin" in them), but I have been poking around with the audio probe.  Here's what I'm getting: On or off the effect has a strong sound, just no chorus.  If I flip the VIBE switch, no sound at all.  Using the probe IC3/IC4/Q4/Q5/R48 are getting no sound.  I am getting a very faint sound from IC5/Q3/Q6.  I have reflowed everything, and double checked values.

There is a drawing on the front of the build doc with a pic of the board, and a bunch of colored lines, but I'm not sure what they represent.  There is a thin maroon, thick maroon, thin blue, and thick blue line.  If anyone knows what each represents that might help me debug too.

Thank you in advance for any help or ideas,
Paul.

Hello,

No, it's a Diablo Chris board.

Thanks, the power board is my bigger problem.  I'm not sure what diode it takes, and if it's a split rail.

Tech Help - Projects Page / Agua net switch question
« on: August 13, 2019, 04:23:53 PM »
I've got a question on the spdt switches  the Agua Net.  There are 3 lugs on the board, but it it looks like the third lug isn't connected to anything if I'm reading the schematic right.  Could I use a 2 lug on/off switch and not connect anything to the third lug?

Thanks in advance, Paul.
