Triangulum poop?

[Radkins80]

Just finished my first Triangulum boost. Very noisey pedal and VERY ice picky. It also likes to cut out and go microphonic at high setting of the level knob. I have reflowed all solder joints and double checked all connections to no end. Either I got a bad component or this thing is just not what I expected it to be. Not a fan.

Sounds to me like there may be a problem somewhere. The Triangulum definitely has an eq curve that is not for everyone or some amps. That being said, mine is not overly noisy and doesn’t cut out or get microphonic. I’ve a/b’d against my Fortin 33 and they sound virtually identical to my ears

Gotta be a faulty component somewhere, i guess.

more likely a poor connection on the board than a faulty component if all the parts are the values called for in the build document. check the voltages on all of the pins of your ICs and transistors and share them along with detailed pictures of both sides of the PCB if you would like some suggestions for problem areas.

I am building two....i guess we'll see if the second one turns out the same way.

I will take some voltage readings and report back sometime tomorrow. Thanks for the suggestions.

Here are the voltage readings from the IC chips and transistors.

I cant get the pictures to upload. ?
