noisy cricket build problems

[dizmaloner]

hey all, new to this forum, was wondering if i could ask for some expert assistance, i just built the noisy cricket mark II and the thing just gives off a terrible squeal, feedback to the extreme, as soon as i turn it on, i have gone through the build step by step (again, and again, and again....) and cleaned the bottom of the board with a wire brush when i was done, checked all all grounds etc. the only thing i can think of is i used non polorized 220 caps... anyone have any ideas that might help me?

anything would be appreciated

Hi dizmaloner, and welcome! I think one of the forum rules is you're supposed to link to the circuit that you're asking for assistance on. So, kindly provide a link, thanks. It will help us help you. 

Generally speaking, you should use polarized caps when the circuit calls for it, so you may have your solution right there.

I hope this helps, and good luck!

I had the same issue dude. I soldered a 100uF cap across pin 3 & pin 6 and it suddenly stopped the squeal and works perfectly.

Got this idea from aanother thread on here...search
