also, the hum interacts with the circuit
it's passing through the distortion (when engaged) and change according to the turn of the knobs
the problem might be at the input or power
yes, I tried different cables; my mogami 2524 with switchcraft connectors and my friend's A setup in his studio and his B setup in his house;
the hum immediately stops when we plug any other pedals (pedalpcb or not) in the place of the Thermionic Deluxe;
now the hum is constant, not only when...
I know nothing about shielded wires, which one would you recommend me? anyways I'll have to import it, it will took a couple of weeks since I can test it; until that I question myself: if the problem is the wire, why every other pedalpcb I built worked properly and coincidentally the 2...
somehow it's worse;
now it's making the loud hum on bypass even if the pedal is lifted 🤡 same thing as the previous build, after a couple days it stops working properly
I did it on both in and out jacks with a nail sanding thing;
I really had hope in this, since the enclosure, knobs and circuit design are the only 3 things in common between both builds, but nothing changed; the noise still remains
A: My soldering iron is a cheap 30w without temperature display and I tried to make the soldering just long enough for it to work, afraid of frying anything;
I'll try sanding it;
just the in/out jacks or the power one too?
@owlexifry
This is the second/current build, that I built with all the careful in the world, so no cold solders, no connections/solders (that shouldn't touch) touching, no fried components, etc
I'm using some different power supplies:
- the main one I use to test my pedals is a single pedal Strymon power supply that came with my Strymon Timeline (great quality), it works great with every other pedal;
- I used 3 different others that I just know that work well, including the main one...
I built two Thermionic Deluxe:
- the first one was from this post, and god, you guys have no ideia how much I struggled to find the problem, but still no success
- since my friend paid the material so I could built a Thermionic Deluxe for him and the first one didn't worked, I bought new PCB +...
update: I redone all the in/out and power connections and re-soldered the mini pcb on the 3pdt; I didn't had shielded wires, but this time I at least used copper wire; still lots of hum.
I went to my friend who is an electronics technician, he couldn't find the problem;
we even went to his boss...
I remember the solder from one this points touched the other while I was working on that switch; but I heated it again until it separates;
I will disassemble the thing and redo the connections in this switch 😢 at least now I have a solder sucker thing that I didn't when building this
