No sound through Steel Singer Clone Circuit - wonder if it's the JFETs

[Fraggy0117]

I need some help troubleshooting a stripboard clone for the Vertex Steel String that's a gift for a friend.


Here's the layout: https://tagboardeffects.blogspot.com/2018/03/vertex-steel-string.html

Here's the schematic (page 2): https://www.pedalpcb.com/docs/SixStringStinger.pdf

Here's a gallery with everything: https://imgur.com/a/B9VLxn7


Notes:

• I'm using surface mount J201s from Tayda and it's my first time soldering SMD JFETs
• I checked every resistor as it went in and all were in spec
• I did not check capacitors before soldering
• I check continuity after soldering each piece - especially if it looked like it bridged
• the pots are sloppily connected because I was just testing before I boxed it up with properly measured wire
• With an audio probe, I get audio up to (and including) the gate of Q2. After that, nothing. I worked from the "in" of the stripboard
• I do have continuity between the leg of the Q2 gate and the solder on the socket, so I don't think it's socketing badly
• I also have proper continuity between the legs of the JFET on the pads and the corresponding lead
• I am unsure how to tell if I damaged the JFET when soldering. I did a few things I found on youtube, but if you have a specific process to test, please let me know.
• I tried to check voltage per the sidebar, but couldn't get any voltage on the gate of Q2, so I stopped. I did get 9v from the ground and 9v-in rows of the board
• I wiggled every part as It went in, and briefly checked again the first time it didn't fire up so I've pretty confident that there are no loose pieces.
• Voltage for the gates of each JFET: Q1: 0 Q2: 1.04-.63 Q3: 4.07 Q4: 0
• measuring from the +9v to the ground on the stripboard I get 9.18v

Do you have any ideas of what to do? Any followup information you need?

Figured it out, no need to respond.

no no - is need to respond. two things - welcome to the forum, and, as I've just spent 10 minutes staring at yer boards and chasing links, the least you could do is tell us what it was that you figured out. it's only fair.

That's fair - it was a pretty stupid thing so I didn't want to waste anyone's time.

It turns out one of the legs of the Q1 J201 wasn't quite on the pad of the adaptor board. I didn't catch it because I got continuity between the leg and the blob of solder near the chip but it turns out the leg wasn't in the solder. It was so small I couldn't see it the first few times.

After that it all worked perfectly right away. I only found it because I was removing all the J201's to check all readings against each other.

Thank you for looking through everything, sorry to leave you hanging!
