Any ideas? :)Anonymoushttps://www.blogger.com/profile/13920234661701108896noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-76414306231556580802014-09-28T21:55:28.233+01:002014-09-28T21:55:28.233+01:00Doh!

I've built two, and neither one is working. When the effect is on I can hear the 'crackle' when I adjust the bias, but output is nil to *very* low. I've tried two different offboard wiring styles and flipping / different transistors. Anyone else ever encounter something similar?<br /><br />FYI: I am using a 2n5088 tranny and 1n4148 diodes.

The only difference is that the vero layout has an additional cap for power supply filtering which I omitted from the tag layout to save space. It shouldn't make any audible difference though unless you have a dubious supply that causes noise. The vero also has a switch to take the diodes out of circuit, but most people will want them in anyway so it's not a necessary mod.IvIarkhttps://www.blogger.com/profile/08416945174853142251noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-29733746508236896502011-08-22T04:05:31.111+01:002011-08-22T04:05:31.111+01:00Hello Ivlark what would be the difference between ...Hello Ivlark what would be the difference between the two almost identical COT50's (not the Briggs mod)Joel Angelhttps://www.blogger.com/profile/10550516444013486495noreply@blogger.com
