Post subject:  The Missing Parts List

OK, white flag. I've searched and searched and can't find the parts list for this headphone amp.
Do you know where I might be able to find the parts list for this 6DJ8 Tube Headphone Amp Project?
thank you
Eddie

Ebay for NOS valves, valve sockets
Element14, rs components and mouser

Aliepxress or directly taobao from China most recomended, expect to wait 2-4 months on shipping by sea.

It is assumed that you would buy parts based on the schematics. However, I believe that this is a complete parts list for this project with the exception of maybe some terminal strips and other miscellaneous hardware which will be specific to your build.

Lines 1 through 11 are for the actual amplifier and lines 12 through 29 cover the power supply and case.

I hope this helps.

I put together a mouser list for my choice of parts here:

You'll need to find an enclosure, tube sockets, tubes, and your choice of volume knob. I used eBay for most of that. I didn't use a filtered IEC inlet as the schematic suggests, though I've found it doesn't matter much for my build. You'll also need to source your own wiring, heatshrink, etc.

Is that parts list intended to be plugged in to a 240V electrical wall outlet or a 120V outlet. I see some differences in comparison to the specs that Bruce put into the original project webpage. For example (AC Power Entry Modules AC RECEP WITH DUAL FUSE HOLDER 10A 250V) other parts too. Just wanted to confirm, please. thanks Eddie

It will work with either - 10A/250V is the maximum rating. The power switch is also rated for 250VAC and a couple amps. Iā€™m in the US so I built it for 120V successfully

As long as you select a transformer with a 240V primary, you should be good to go on 240VAC mains. It's essentially the only variable at play; the IEC inlet and related parts are all universal.

Just completed my first tube build. The 6DJ8 Headphone Amp Project
was a fun learning experience. I designed and etched a printed circuit board
for the power supply, which attaches to a 2ā€ x 2ā€ steel tube, that I used to shield
the input transformer. My B+ voltages came out at 156 vdc. The sound is clear
and clean and wonderful to listen to. I do have some hearing loss, so the volume
is usually set almost full volume when listening to my Ipad. I plan to test for THD
and linearity soon. Thanks to Bruce for an elegant amp design!

Thank you much for the build! I am excited to get this up and running. I put together the first fun, and I seem to be running hot on first 4700 cap. I cannot seem to figure why. Removing it from the circuit resolves that issue of course, but there is a strong 60hz hum the tubes are running hot. Thoughts as to what I may have wrong? I can provide voltages if that helps. Thanks!

Thank you much for the build! I am excited to get this up and running. I put together the first fun, and I seem to be running hot on the first 4700 cap. I cannot seem to figure why (reading of 7.9VDC). Removing it from the circuit resolves that issue of course, but there is a strong 60hz hum regardless or and the tubes are running hot. Thoughts as to what I may have wrong? I can provide voltages if that helps. I have checked all tube connections, and am left scratching my head. I am not a novice to amp building, however, this is a bit of a different design I am not fully used to.
