DIY EL84 Project: Part 3

Circuit Board Assembly: Finally, We Get To The Fun Part!

News Flash: Potential amp builders living in the U.S.A., please note: Antique Electronic Supply, https://www.tubesandmore.com/ is offering a 10% discount on all Hammond products through to March 2, 2020.  If you have been sitting on the fence, now might be the time act.

***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.
