Title: Choral Reef boo boo
Post by: chongmagic on December 08, 2019, 05:21:40 PM
So I didn't reach the switching schematic correctly and put the C6 cap into the C5 spot. The pedal works and all the voltages are within spec of the build guide. I used the soldered in jacks with the switching board so removing C5 is going to be a pain at this point. My question is as the pedal works as is, is it bad to leave it as is or should I remove C5? And can I just put in C6 as per the build guide with leaving C5 in place since there is no charge pump in this build?

Build pics for reference.

C5 isn't connected to anything without the charge pump. You're fine to leave that in and install C6.

That is what I figured but wanted to make sure. I'll be sure to read the schematic more carefully next time. Thanks Benny.

No problem. On the upside, that build has the oddest of requirements with the switching board. All the others are rather straightforward.

Yeah this is my fourth VFE build and I am still no expert on reading schematics it seems lol.

One last question, will it make a difference in the sou d of the effect?

It will provide a more stable bias to the TLE2074 and reduce power/switching noise. That's the only decoupling cap on that rail.
