Necro-bump...

HAs anyone verified any of the layouts on this thread?

I am interested in doing a 1-for-1 PCB clone of the original Meatball and this is the closest I have seen. Can anyone verify that ANY of these layouts are good to go?  ;D


May or may not be what you're looking for, but I've been tempted to grab alanp's shared oshpark PCB of the meatball from here:

Thanks John but, I am really interested in a faithful reproduction of the original Meatball PCB. Looking to do EVERYTHING DIY!  :icon_eek:

I built it with my layout and it worked. I should warn you that the design has some issues I commented in a previous post, but if you want to build it, go ahead.

In case anyone wanna know, I'm currently working in a similar design based on the supertron (I think someone mentioned it in this thread)  Here's the original project:

My goal is to house this in a 1590 type enclosure, so I'm changing the rotary switches (that take a lot of space) for toggle switches (which doesn't). I'm trying to mod it to make it work with a single power supply, not bipolar like the supertron. I also changed the input/output/send/return for the ones I commented in my previous post.

Bump...

Just wondering if the Pedal1 and Pedal2 jacks need to be isolated from the enclosure.

I built this and I am getting great results OUTSIDE THE ENCLOSURE. 

When I install it in the enclosure, I lose effected signal when I plug in the Output plug and I get voltage on the enclosure (2.5VDC)

Thoughts??

On the wiring diagram above the jack third from the left, can't read what it's called, appears to have its sleeve connected somewhere other than ground so needs isolating. The others all have their sleeves connected to ground.

Thanks Ian... I GOT IT WORKING!!!  ;)  :icon_eek:  :icon_twisted:

BTW... I just went ahead and put in isolated jacks for BOTH of the Pedal jacks. After doing this... it still wouldn't work  :-\

BUT... I found a bad Output enclosed jack. First "jack"" that has ever gone bad on me. Replaced that (after installing the isolated jacks) and it fired up good!
