I’m so glad to hear you got it working again! Good job!
If you wanted to re-install C17 you might need to get creative with how you wire it. The original pads on the board are not able to be used so you you’ll need to run jumper wires from the cap leads to the output jack tip and pin 3 of Q3 (as per the schematic). But that’s only if the relay click starts bothering you. If not, just keep it as is.
