Asking as I'm sure someone here has had one of these apart at some stage. One of my 9V 200mA outputs intermittently drops out, then instantly turns back on. Maybe once an hour. All other outputs are going well. Anyone fixed one of these before?

I had one of these. After a couple of years the outputs began intermittently dropping out too. Turned out to be grime in and corrosion of the leads they supply, plus the input jacks. A good clean out with contact cleaner sorted them out. Hopefully that's all that's up with your one, otherwise there's that bloke down south that saves busted pedals and stuff (it could also be a broken solder joint for that jack). I forget what he calls his bizzo though. Someone here will know who I mean.

I’ve had my CS7 apart twice, first time it was dropping in and out on one of the 500mA outputs. Tech traced it to the cheap electrolytic caps, we replaced a few and it sorted the issue for around 2 years until recently I was getting a bunch of noise from it which was getting progressively worse. opened it up
Again and replaced all the electrolytic caps I could practically replace and it fixed the issue.

Bad filter caps as Reg says, dodgy DC jack maybe, or the regulator on that particular output.

Cheers all

That's the one. I have never dealt with him, so can not vouch, but he seems legit and has fixed lots of pedal it appears.

New caps in. Hasn't faulted again yet, but needs a proper soak before we'll call this fixed. Clearing off the workbench for this was a good excuse to repair a joycon at the same time

Might be.

Just a few.

Nice one.

Meh, the output died completely.

Will change the Reg out... Just checking, looks like a LM1117 from these markings and the pcb. Anyone able to cofirm this? Might ping a quick email to Truetone otherwise.

The adjustable version of the LM1117 by the looks of the making and the silkscreen on the PCB.

Cheers Blake, that's what I reckoned too. Have pinged them an email anyways, will post if I hear back

I've often found that while companies aren't very forthcoming in regards to schematic requests, many will tell you a specific component value / type / part number. If you haven't already, it might also be worth checking some of the components on the bottom of the PCB that are connected to that regulator just to be sure.

Hey Corey,
Thanks for writing in. I apologize for the late reply. LM1117 is the correct regulator on the CS7. If this does not fix the problem let me know and we'll be happy to help troubleshoot.

I hope this helps. Let me know if you have any other questions.


All the best,

Hopefully, you can source one locally.
