If naked tube sockets are your thing, you’ve come to the right place.

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, 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.

Part 2, Attachment 6:  Volume Pot Mounting Plate


Perform the tasks for Part 3 in the attachments below

Attachment 1: Board Prep. & Tube Socket Assembly

Attachment 2 (Revised): Resistor Assembly

Attachment 3: Capacitor Assembly

Attachment 4: Terminal Block Assembly


Attachment: Simple P-P Board


Next time, in Part 4, we’ll assemble the transformers, circuit board and other parts to the chassis and connect them up.

    Is the DIY EL84 Project amp for sale. Like do you have resistor paks and parts?

    I’d love to build this

    Good news Dave! Boards are available again from Order soon before they are sold out. There are several build threads on the Tubes/Valves forum at

    Cheers, Steev
