Definitely would raise my eyebrow if replacing a bridge rectifier cured the hum. Maybe some heat caused deficiency in the epoxy package that encases the silicon and the diodes started capacitively coupling to each other. Only other guess I'd have is that some electrolyte got to the leads and...

Yep, diode shouldn't matter tooooo much. Keep VF similar, make sure its rated for the current, peak and continuous reverse voltage and make sure that the reverse recovery time is good enough for whatever its rectifying. US1G is good in that position, which I guess is why they recommended it :P...

You summed up my thought process exactly. I wish I didn't have to justify my existence and value through being able to get a regular job and making money for someone else while I get a small portion of the value I create... but that's the pressure society has placed on me, my family has placed...

I had an unexpected summer in my helping out of someone near and dear to me. They ended up spending most of the months couch surfing, mainly on my own couch. Thankfully they're quite literally in a better place now and have a mostly stable living condition :) Haha I got diagnosed with ADHD...

Hey all. Been a while since I posted. Very busy and strange summer :) I'm looking at the BOG fuzz schematics (https://docs.pedalpcb.com/project/Marsh.pdf) and I'm wondering to myself what the goal of the buffer at the front is. I can tell it's a relatively standard silicon fuzz face (though the...

Unfortunately, I see a lot of potential problems with your soldering that could easily be the cause of your issue. There looks to be many points at which those wires on the underside of the board could short to somewhere they shouldn't be shorting. Do you have a multimeter? You should use that...

Increasing the 100kA pot to a 250kA pot would help, by how much, I'm not sure. It sets the gain for the LED portion of the vactrol. I wouldn't go over 250k because you're really pushing the limit on how much gain you should get out of a single opamp stage. I'm not sure if changing the BAT42...

Hey could you show us how your wiring and solder joints? Just might give us a basic idea of where you might have gone wrong (y) This is almost definitely random white noise and interference being picked up, so at a guess, you probably put something to ground that you shouldn't have, and the...

What voltages do you see coming from the socket for the the Daisyseed? This is probably the number one place to start with digital stuff. Don't even plug the Daisy seed back in, just put your multimeter into the the socket holes.

This is my go to method to! Glad to see independent validation of my process :P

I am gonna reverse engineer this power supply at some stage, because it is very good, but has some less than perfect design choices. (Power LED runs on the 9VAC transformer and the fact that the 9VAC is derived from a transformer on the mains means you still have to choose the input AC voltage)...

You never know what you can do with a second power supply! (It's gonna be a lot more pedals :P)

Yep! One bad diode brough down the same output group that you're having issues with. Hopefully there's nothing else wrong, but i suspect the culprit is one of those diodes. You can literally remove it and you should see the voltage come back up to 9 point something. With a load of ripple mind...

Hello! I was meant to comment on this like a week ago at OP's request. But life happened and I had to look after someone close to me. I intentionally purchased a CS12 with this defect and in order to fix it. Not a lot of resources online - Truetone seems to be good with warranty repairs, as...

Yeah no bother mate! If it's a similar problem to mine, it'll be an easy fix (fingers crossed). I'll put the details on that thread when i get home. I think the reason you don't see any documented fixes for it online is that Truetone seems to be good for warranty reapairs.
