One thing i did notice is the input 2.2uf cap is the wrong way round? Apologies on the delay of things but im recovering from a serious illness. Not the crqzycovids. But no sound out of this thing but i am getting a signal through with the power disconnected.
Hmmm, 2,2uf cap has positive leg in my schematic? BUT the 22uF cap was connected wrong....(I still get easily confused with PNP fuzzes with normal power supply...). I had to shift some things around unfourtenly for the updated layout.
Aw, that sucks man, hopefully you get fully recovered soon and back on track with the solder iron.
Cheers man im getting there. So im looking at the schematic on fsb, it seems the link from 9v to the top row should be from ground and a link 9v to fuzz 1 is needed? https://www.freestompboxes.org/viewtopic.php?f=1&t=29748&p=279737&hilit=Dunlop+fuzz#p279737
Well ive actually got some of the exact ones from the fuzz as i did a coupla mods for a buddy who works at GAK. Upgraded them to ac128’s and added a power jack so he can remove the battery power. In this one ive got thr original transistors but im gonna have a play. Ac128’s sound the bomb in there but i wanna see what else i have.
Yoooouuu fliiiippiiiiin leeeeggeeeend!!! Thank you man. Will whip this up pronto xx

ReplyDeleteApologies on the delay of things but im recovering from a serious illness. Not the crqzycovids.

Sorry positive leg to the base of Q1.

Yo, move that bottom link leg from 9v to ground and tag that sucka xx workin xx
ReplyDeleteCheers man, tagged! Which trannies is in there?

What a great circuit, it uses PNP transistors and its centre negative. Perfect!!! Used NKT275's (not original) and it sounds ace!!!
ReplyDeleteJust put this together using some ac128 transistors...only a quick quiet test as the kids are in bed, but it sounds smooth and lovely.
ReplyDeleteFuzzhead...thank you again!
Just amazing.
And teddeeh, thanks for your verification work. Hope you're fully recovered and doing well.
