A Super-Simple 6DJ8 Headphone Amp - Page 32

post #466 of 490

Here is finished version of my amp, with oak side panels, linseed oil finishing.

 

Now amp have its own name - Rock'n Glass headphone amp.

Name come from amp's powerful sound and hybrid nature.

 

 

 

 

This one exemplar are with lin outputs.

Lol, I was just going to tell you tonight that I bought some hex wrenches, and got the sides on... Mostly. Two of the holes didn't line up, but I thought I could copy the screws from the side that did fit using Photoshop. Looks like you changed other external parts of the amp as well... Did you fix the bias reading leads to be available in an attractive way like you wanted?

Nice photos. A little reddish and the bottom photo was slightly dark, but that kind of thing can be fixed in a few seconds inside photoshop.

Are anyone of Super-Simple 6DJ8 Headphone Amp builder or owner trying this amp with  Beyerdynamic DT 990 250 ?

post #469 of 490

I have the dt990 250s beyersmile.png. Can a board(s)/kit be purchased? Very elegant amp design, I like it! Thanks!

Thanks, stupidmop!

At the moment I haven't any boards left, only 2 ready built amps.

Few forum asked about boards too, so I think I am going to order next bunch. May be available in 2 weeks or so.

 

I ask about DT990, because someone wanted ordering amp for his phones.

Cool. I'll look forward to building this bad boy. biggrin.gif Thanks Zigis, can't wait!

post #472 of 490

Finally boards are ready.

If someone are interested, I have 4 or 5 PCBs spare.

Got mine! Thanks Zigis

Just started mine! Although now I have to wait for the bulk of the parts because no stores in Australia seem to carry nice caps or any transistors. Going to use a nichicon 4700uF cap for C103 and Vought some rifa caps for c101 and c201, the tube is gonna be a JAN spec Philips 6922 and I'm gonna use a Hammond case with the top cut off to let it all breathe. Also had to order an IRF510 instead of the other one. I'm getting very excited for all this stuff to come so I can finish it off

Are there any boards left?

 

I fancy building this!!

post #478 of 490

PM  if you are interested.

Just finished mine! sounds really good! I get a 'whiney' high pitched noise through mine all the time though.  It starts out loud and slowly gets quieter, I'm wondering if it's my power supply, or something to do with the tube heating up?

 

EDIT: after leaving it run for maybe 5-10 minutes with music through it the sound has turned into more of a light static.  It keeps disappearing for a little while, and then coming back
