    Is it worth trying to fix a power supply?

    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...

    Is it worth trying to fix a power supply?

    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...

    What's up with the buffer in the Deep Trip BOG?

    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...

    blending circuit errors using buffers

    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...

    Need slightly heavier compression from limiter dial / effect

    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...

    blending circuit errors using buffers

    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...

    Failed Terrarium/Daisy build - need help!

    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

    Is it worth trying to fix a power supply?

    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)...

    Is it worth trying to fix a power supply?

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

    Is it worth trying to fix a power supply?

    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...

    Is it worth trying to fix a power supply?

    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...

    Power Supply recommendations? (Anything inexpensive and reliable?)

    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.

    Power Supply recommendations? (Anything inexpensive and reliable?)

    The unfortunate reality is that a lot of power supplies suck. And they have gotten a lot more expensive of the past couple of years, unreasonably so compared to inflation. Daisy chaining will sometimes work, until it doesn't. My board is rather complex and requires a decent amount of mA, so i...

    Genuine Question - What's going on with the noise complaints with the Electro-Smith?

    Coulda stopped there! Being a massive Mike Oldfield fan, I love the SOUND of Boogies, but being a watcher of Psionic Audio's repairs, I know I am never ever dropping my hard earned cash on one of their ticking design time bombs. Or already set off design bombs. I'm learning to build my own amps...

    Genuine Question - What's going on with the noise complaints with the Electro-Smith?

    I don't doubt that stuff like bad grounding contributes to this problem. Most analog pedals you see people build on this site and elsewhere do not observe a 'proper' grounding scheme. That's not shade I'm throwing at all you guys out here, a lot of my earlier pedals have sub-optimal grounding...

    Genuine Question - What's going on with the noise complaints with the Electro-Smith?

    I want to get into building and creating digital effects, and while the the Electro-Smith Daisy looks like a great place to be, a very popular thing on this forum seems to be posts trying to troubleshoot and fix noise issues. Different revisions seem to have different problems. While I'd be...

    Yamaha DG-1000 - Input opamp gain increase

    Hey y'all! I have a Yamaha DG-1000, a digital modelling rack pre-amp that is in my main rig, which I love playing very much. One problem is that the rack pre-amp is missing something from the combo and and head versions - a HIGH input that raises the gain by some amount (I can't tell by reading...

    Should I avoid making input and output signals 'cross' each other?

    Thanks for the response! I suspected as much tbh, I more didn't want to come up with a solution than anything else. It should be easy to fix, I'll just add another row of perfboard above the ground line and bring the signal from there to the output, so it doesn't cross the input anymore. I...

    Should I avoid making input and output signals 'cross' each other?

    I'm designing my first perfboard layout for an adaptation of a silicon buzzaround from mac over at diystompboxes. I have a feeling the answer i yes, but I'm wonder if I should avoid putting bringing the output signal across the input of the board in order to avoid stuff like cross-talk and...
