I also built the additional stages mod on the same perfboard.
Heres my question
Can I make the additional stages switchable and if so how please?

Q1
the 12v zener Is 500mw enough or should i go for 1w?
Q2
I'm fresh out of 220uf 25v  so I subbed it for a 220uf  16v.  This should be ok right?
thanks
Rich

guys
i have the currant lover all populated and set up to start biasing it as per pdf.
I'm not getting a signal on the output.
so I start probing and the signal goes as far as mn3007 pin 3. no output on pins 7 or 8.
I bought my chips on ebay. could I have bought a fake. Do you think that could be the reason.
I've invested a lot of time and money and effort into this one effect, the biggest most complex build to date and I'm bitterly dissapointed. I hope I havent blown it all together.
one other thing i've noticed is if i disconect the gnd to amp i get a signal.
Please help. If its just a matter of getting a better mn3007 then fine.
I'm building it on a prefab qaulity pcb.
thanks
Rich

Hi guys
I've just built the nautilus on an etched pcb and all I hear is distortion no bwow wow. Lots of boo hoo. Haha
I double checked for resistor values
I can't see any bridges.
I probed it but it only passes clean signal or distorted depending on rotary switch position.
So I'll throw out the voltages and see if anyone can spot anything
Thanks guys

Guys I'm bulding the nautilus on a pcb from a friend.
I have a couple of questions if you will.
My vactrols are on order but which way are they orientated please
i note that on the single sided layout (madbeans) that there is a mark (+) on one side of the vactrol representation on the overlay.
and although i dont have the vactrols yet i believe theres a white dot printed on them.
Does the (+) mark represent where the white dot on the vactrol goes?

Which charge pump ic5 would you recommend
mx1044scpa?
tc1044scpa?
icl7660scpa?

I've probably asked this last question before but my pc is playing up and i cant find the thread so any help would be appreciated again
Rich

Im making the version one (single sided board)
Im confused because the layout  has a C10 and neither the schematic or BOM states a value for it
can you help please?
Thanks
Rich

Has anyone here built a through zero flanger please
If so which is best.
I've got some mn3007 and 3101 on the way plus some 78L12s
I was going to do the ibanez fl301 but then I discovered the tzf's mmmmm intresting.

I've seen the Schoon Toon here and the build doc but I'm affraid I dont understand the schematic could some one throw some light on it please.
inputs?
outputs?
power supply?
Stumped

heres the build doc. I hope its ok to post it

Hey guys I have a question.
Would it be ok to substitute the TL071 Vref buffer with half of a TL072.
I know the pinouts different.
Thanks
