How Do I? Beginner's Paradise. / Re: Damaged cap?
« on: December 01, 2019, 05:49:02 PM »
I think the power is reversed, that's why no LED, but double check.  Since the power is going through a protection diode, I might suggest to try switching the leads,  but since you have some nice transistors you might want to wait for help from some of the fuzz jedis.  I'm not one, they actually give me a lot of trouble, even though they are simple.

You might double check the build doc for the version you picked (the down side of "ultimate tweekability") .  Maybe the power is reversed or there is a NPN PNP mix up.  Does the LED light up?

I'd go with the buffered bypass.  Considering the amount of engineering in this circuit, I'd wager that buffer has some positive contribution to the sound.  Most Aion projects have a true bypass option, but he says in the build docs that "buffered is almost aways better".

When you say the standard 11mm electro's won't fit do you mean they are too high for board that goes on top?

Yes, too high.  Also, there is no place to bend them out of the way.   

Also, I wanted to add a tip.  I have built two of these and both quit working after being on boards and stomped for awhile.  What happened to both was that the bottom PCB slipped out of the pin headers.  I added some adhesive foam to keep this from happening and they are both working great now.   I bought the pin headers from Tayda, so, that might be the issue.

Happy about the necrobump, I really loved this build by Gordo.

I took some picture of the populated boards when I built mine, before boxing, the link is below.  I think Kevin prefers WIMA caps, I think size wise others will fit.  The electos need to be the short ones, however.  Standard 11 mm high caps won't fit.  One of the nice things about this project is the mouser list of parts linked in the build doc.  You can upload the whole list to mouser and then remove the parts you already have from your cart.

I'm looking for some advice from anyone who has done repairs on these.  A friend of mine asked me to take a look at his friends vintage MXR 117 (so, friend of a friend to me  :o).  I told him no, because I didn't feel comfortable working on and potential breaking something that valuable.

Today I got an email from my friend asking if I had a spare Reticon 1024A lying around(!), which has me worried they are planning to start pulling parts.

So, should I keep my original inclination and not get involved, or try to save this pedal from certain destruction?  I have a scope and could at least trace the signal out for them.  What do you guys think?

Here is the description of the problem:
"signal is not being bypassed when the pedal is off, so no sound comes out...  when it's activated, the signal comes through but none of the effect is present, so, no effect, only clean"

General Questions / Re: Flintlock Flanger (ADA) - Auto Trimmer
« on: November 13, 2019, 01:03:49 PM »
Thanks Scruffie.  So, if it is set to sweep 70k to 2.6M and you move it from there,  would it move to say 75k to 2.5M or more like 75k to 2.7M?

General Questions / Flintlock Flanger (ADA) - Auto Trimmer
« on: November 13, 2019, 11:52:21 AM »
I was wondering what the function of the Auto trimmer is conceptually?  In the Flintlock set up, you adjust it until the frequency sweeps between the lowest and highest value.  However, I've noticed that it seems to be either working or off depending on where you set it.  Is there a sweet spot on this trim?  If so, what is it doing to the signal and how can it be set to the best position?

Since you are ordering from Newark, I usually look for a couple of specific brand/series, like  WIMA MKS2 or EPCOS B32529.  Then scan for the "red star" labeled ones they seem to always be blowing out for pennies.  Then I stock up  ;D  Shipping on Newark is expensive though.  Sometimes, even with the red star buys, it is cheaper to buy stuff from Mouser.

Please please please someone offer up painting, labeling, and clearcoating services as a prize.  Really, just about anything related to successfully finishing a pedal would be excellent.

Finally, something I can do!  ::) I will offer one labeled and drilled Tayda enclosure for the project of your choice.  Graphic design based on input from the winner with one iteration of edits.
