Let me start off by saying hello and that I am new here. So, Hi!
I purchased a RullyWow ChuggaPre PCB (I know it isn't PedalPCB but they were out of stock and I have bought a few from PedalPCB but haven't started them yet)
I built this preamp and it works in the sense that it boosts the crap out of the horrible squeal that is coming out of the amp. One thing I did notice is that the TL071 (I believe I am using a TL072CP) got extremely hot when I plugged it in and tested it for the first time. I switched it out for another and it does not get hot anymore.
There is no other reason the squeal would be happening other than the pedal. Tested with Mesa Boogie Mark V and Peavey 6534+ and both have the same results.
Is this possible something power related? Like DC getting somewhere it is not supposed to be?
I have double checked all of my solder joints, cris-crossed wires, things touching that shouldn't be, I/O jacks are wired properly, I used 3PDT board (could it be something on there?) and I am damn near positive I didn't install anything in the wrong place or with the wrong value. I really took my time verifying everything was going in the right spot however, it still is possible I screwed up. I checked parts placement but could have missed something.
I am very new to this (this is my very first build).
You guys owe me absolutely nothing so I appreciate any help or advice given.
I am happy to provide any more information or details needed.
Thank you!
