My first build. Happily I have some tone coming through but when switching the DPDT boost switch I lose anything. Any tips appreciated on what I should be looking for (have rechecked all solder joints / have trimmed to 4.9v J113).
If it helps – there does seem to be a boost of treble frequencies when the switch is in the other position and I get tone. I wonder if that means the boost circuit is working but the primary isnt?
