Trouble with Woodpecker

[Haigster]

I'm looking for some help with the Woodpecker Tremolo board. I've checked it over multiple times and the resistor values seem to all be correct. Could someone please look it over and maybe compare voltages on their own 'working' Woodpecker? Mine has the original signal but no effect. Here's some measurements:



thanks for your help.

I had the same problem with mine initially. Turned out to be the bogus 2n6027 I got on eBay. Swapped it for a central branded one from mouser and it was all good.

I got some on eBay that claimed to be real from here in theUS. They were bogus, so I sent them back. Seems like I ended up going to mouser.

Pretty sure it was one of your posts that steered me to mouser/ central brand!

Excellent

I had a chance to try another 2n6027 and that didn't make a difference. I'll don't think my voltages are correct and will double-check my resistor values again.

I ended up replacing both my 2N6027 and my 2N5089. I can't say which one was the culprit -- maybe both, but that cleared it up for me.

Thanks Chris, I’ll try replacing the 2N5089 next.

Apparently there are a lot of bogus 2N5089s and 2N6027s on Amazon and Ebay. If that's where you got them, I suggest picking up some from Mouser or Digikey.

I picked up some 6027’s from a german vendor with 99.5% positive….

Ive got no effect
