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.
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
Hi Dave,
We’re a review website, we don’t sell kits. Please check the links for possible sources.
Noam
Good news Dave! Boards are available again from Tubelab.com. Order soon before they are sold out. There are several build threads on the Tubes/Valves forum at DIYAudio.com
Cheers, Steev
