***Cap upgrade: Our patron decided to splurge on four Mundorf Supreme coupling caps: these cost about $9 US (each) more than the CDE caps that are in the parts list.
***Volume pot: I found a few pictures that might help clarify use of the volume pot mounting plate if a volume control features in your build. I’ve included that as Part 2, Attachment 6 below.
