Title: How to turn this BYOC Amp Selector into one output?
Post by: guitylerham on December 28, 2023, 09:24:21 PM
Howdy,

I'm using this schematic from a BYOC amp selector but instead of two outputs, I only need the one transformer-isolated output (B on the schematic). Looking at this schematic, I'm trying to deduce what I delete in order to get such a result.

I'm thinking I simply delete everything circled in red: R7, R8, and don't use SW1 at all. My gut tells me R3+R4 in parallel with R7+R8 might be important if they reference ground through the opamps. Am I overthinking this?

Thank you, PRR. Didn't think to remove a gain stage!

Works perfect! I was way off with my initial thinking. Thanks again.
