Thanks!

This one will do both.  The schematic omits the -9V supply that's present on the vero, but that's just the TC1044 IC1, plus C1 and C2, feeding -9V to pin 4 of IC2.  You can use a second 9V battery for the -9V supply and simplify it.  Note that R1 (100 ohm) is 0.1% tolerance, not the usual 1%.

So this vero is correct? I can build as shown and it'll work?

That one is for measuring just vgss off. The ones I'm inquiring about are for measuring both Idss and vp.

I'm getting into understanding jfets. Found runoffgrooves jfet schematic that tests for Idss and Vp. Now there are two designs up on tagboard. One has a 47 uF cap, the other has that cap and an ic. These differ from the one I found from rog. Yet I can't find any info on why these components were added. So I was just wanting to figure out how to translate this schem to vero, the one from rog's article. http://www.runoffgroove.com/fetzervalve.html
Schematic for tester is at the bottom.
I've drawn it on paper but I don't know  if it is correct.

So I've recently revisited my chunk chunk build. I noticed I socketed r9 which currently has a 40k in it. Build doc calls for 470k. For the life of me I can remember why I did this, and I can't find any info searching. Any help?

R9/R10 form a voltage divider to reduce the output of Q2 going into Q3 (R10 is also part of the bias scheme for the JFET). So, a lower value of R9 means a bit more signal getting to the Gate of Q3. I don't recall anyone ever discussing modding the 470k value but it might have happened. You can change it back to 470k. It's should not require resetting the Drain trimmer, AFAIK, but that only takes a minute anyway.

Following the schem I was able to see the signal flow into q3. I had no trouble biasing the build years ago. I also found the 470k labeled chunk chunk mod in my spare parts box. I built this 5-6 years ago. I could've sworn I read about that mod on some forum but it's been a long time. Heck I think it was the last pedal I built until now. I'm getting back into it. The pedal I'm currently building has 2n5457s, preamp build. I bought a matched quad set. Although I can't biasing them down to the proper voltage with the 20k trimmer listed for the build. I had a spare 100k so I dropped it in and was able to biasing q1 of that build to 4.25v. Now these 2n5457s are through hole. I have smds mounted to adapter boards on the way. I'm gonna drop one of them in and see if i can bias  it to 4.5-4.25 without changing trimmer. The packaging (great quality anti static) and the stats listed for each jfet has me thinking these through holes are genuine. Or else someone took the extra time and money to make me think they are. This got me to dive deeper into jfets. Which has me wanting to build a jfet matcher. I figured I'd try the j201s out in it when I do. Long story short, that's the reason I opened up the chunk chunk.

Any buildplan for considering? I mean schematics.

You can find everything for it in the archive page at the top of the shop page. Chunk chunk listed under the dust/boost/od section

i get sound on pin num7 on ic 1 and ic 4 but nothing on ic 3 pin 7. even switched ics and still noth on ic3 pin 7

so i got my audio plug. i go to the first resistor r2 sound going in and nothing coming out of it. is it really this resistor?
redid some ic voltage readings im only going to list the bad ones.
pt2399
#7- 1.73v
#8-4.21v

ic#4
pin#3-1.95v

finally order a signal probe. gonna try and find where the signal dies off at

update, sorry it has taken a bit. after soldering the ic socket, everything seems to work EXCEPT the level. i can have level all the way up and can barely hear the pedal. everything else seems to function from what i can hear. tested level pot. its reading a little over 1m when turned all the way up. any ideas?

yeah they are connected. sounds passes through when in bypass. i just  perfer this way of wiring the 3pdt.

update tho.

stupid me only soldered one pin of ic three. so i just fixed that.

another thing i found was that r32 and r33 read 50k. these should be 100k and color code matches 100k.  guess i got two bad resistors. r3 reads 100k just like it should so i know my mm is reading correct.

i checked voltages on ic3. all pins are good now.

pin 7 on ic2 still reads .38, led is reading .39. can this be the problem of pin 7 low voltage?

im gonna try and play this asap to see what happens now.
if still no sound then ill replace those two 100k reaistors and try and order some leds that have a voltage around .7 also order an audio probe while im at it.

any help or ideas will still be pretty cool, thanks.

well theres no sound unless i turn feedback all the way up. then i get a very faint sound of my guitar.

incoming v from power supply is 9.27

im gonna assume i have resistors in the wrong spot or of the wrong value somewhere. any idea where to start?

so im think of doing this project, but i have questions. i see in the bom u can use a LM78L05 instead of a LM7805. is this the one i can sub with(http://www.mammothelectronics.com/LM78L05ACZ-p/400-1108.htm)?
second the trim pot situation. where do u all source these 3362s besides mouser? it appears there is not enough room to use the 3386 trimmers like i did on my chunk chunk build. i usually get everything from smallbear(5% toler caps) and mammoth(everything else).  i even though about using a reg pot(dont know if it should be a log or lin one though) instead of a trimmer so i could adust it on the fly if i wanted to.

im assuming the markings for the footswitch goes as follows
g-ground
L-led
s-signal to pcb
i-from input jack
r-signal from pcb
o-output jack

i asking because i like to wire my footswitch a certain way and wanna make sure my connections to the pcb are correct. thanks for the help
