Triangulum problem

[dlazzarini]

I’ve just recently built the Triangulum build. It’s a working build but something sounds off. When I turn the level up to a decent level or about half way up I get a really bassy heavily saturated sound that starts to cut out and break apart when heavy power chords are hit. Like it’s being overwhelmed. Ive got 9volts on pins 1/8 which are connected at VCC from what I can tell I’ve only got 5.6 volts

I don't mean to sound critical, but there's quite a bit of copper showing where the pcb has been scratched, it may be an idea to check for track damage or bridges where you can. I recommend using a pcb holder for soldering (the rotating double clamp ones rather than the crocodile clip version). Good luck, the Triangulum is great.

Yes I have since acquired a good PCB holder. This was one of my first goes at it. I have the Triangulum working fine now and it is a great pedal. I’m on about my 7th pedal now and I’ve greatly improved thanks to the folks on this forum and my persistent thirst for knowledge.

Pretty neat and clean work, congrats !

Thank you. I’m now working on the whole water slide decal thingy. I’m finding that the color of the enclosure has a bigger impact on the final product than I anticipated. Gotta figure this out.

I had it working for like 45 sec then stoped , i did replace Q1 and Q2 and put the pot the right way. I spent hours trouble shooting so ..in the live and learn box of mistakes and buy another board and start over !

If you set it aside, don't be surprised if you pick it up after a few more builds and see something to fix that will do the trick.

Thank you for the words of encouragement ! I looked this morning found another cold solder joint on a ground wire also Tadya sent me a solid wire that i used while bending it broke..fixed... but i thought that might work since the A5k pot is detached and used on the pot and wires going to breakout board might keep it suspended vs a more flexible wire to give you a insight to my thinking....but could have used foam to separate and keep from touching..

But my $25 iron got to hot and when touching like 3 seconds using a solder sucker the whole metal ring came out of the board...it was so hot i watched the fine tip slowly bend before my eyes..lol...bought a Hakko Station this morning, that weller was rated at 925 degrees i think ,way to hot !

Ill just buy a new board, populate and solder up the input/output jacks, power and breakout board and pot...Try again !

Words to live by....i got it working !

Went back thru every single solder joint , anything that i glanced at twice i reflowed the solder...then rechecked again !

Didn't have a PCB pot to hook up to the board used a reg one , in cased it foam so nothing shorted and success !
