Boringer, thanks so much. I said I was done with upgrading but i must admit the thought of DSD was too strong to let go of!

does this mean that you also have a second t5p ....

post #1653 of 3704

btw, when typing my last message, i remembered something and have repaired my t5p. the cable was broken near the y-split, so i have replaced the y-split by a 3.5 mm jack.

 

as with my grado prototype headphone cable i now can use different interconnects as headphone cable, for example one made out of an eight wire grado cable and one made with 4 wire pure silver axmann axiom III.

Oh thats great, I am looking forward to hearing your thought on the T5P with the amp!
As per headphones. I have a pair of D5000's that I gave to a friend when I got my LCD's but they did not like them and returned them so I will give her those, The sound really good with the 801. I did the Jmoney mod with them when I first got them years ago. so they have nice leather pads

dear thread members, here it is:

 

THE NEW TU-05 - TWIN OUTPUT

today here was a public holiday, so i spent the afternoon to modify the tu-05 in the way i posted before (version 2 - power jack in front, additional neutrik 6.3 mm jack at the place the power jack was before).

 

front view - power jack top right - as symmetrical as possible but did not want to damage the potentiometer while drilling and shaping the hole:

 

 

rear view with neutrik 6.3 mm jack - what a nightmare to get this large hole done:

 

 

front view with open case:

 

 

rear view with open case - you can see the additonal 3 cables bundled with white shrink-on tube - i used cutted pieces of the broken beyerdynamic t5p headphone cable directly connected to the output transformers:

 

 

top view to see the big hole bottom right before adding the additional cables:

 

 

 

some horror pictures that may prevent you from doing the same:

 

my workbench:

 

 

protecting the amp with tape before drilling and shaping the big rear hole for the neutrik jack:

 

 

drilling a lot of small holes to then cut and shape the resulting big hole for the neutrik jack:

 

 

drilling the new front hole for the power jack while protecting the amp:

 

 

measuring the size of the existing power jack hole:

That is impressive work! How does the 6.3 jack attach to the case?

post #1657 of 3704
Well GG, my flabber has truly been Ghasted! Did you take the whole amp apart to a achieve this modification?

Incredible work, my only concern is confusing the input with the power socket but I guess if one is careful all will be well.

Your a brave man, I would never attempt such a thing as I am completely incompetent with this sort of stuff, my hats off to you sir!

Now, is there any change in sound quality with a higher quality headphone socket?

Just saw the new 'horror' pics. Makes it all the more impressive, actually, phenomenal, really!!

post #1659 of 3704

if you mean how to keep the neutrik jack in place - i had no screws but i love superglue.

Holy modification batman! The "Horror" pictures just make it even more impressive! Have you posted these to Shikada san, I bet he will be impressed! This amp seems to encourage mad scientist behaviour biggrin.gif

GG, do you do Facebook? If not, can I post these pictures on ASP's Facebooks page?

That's the only part of your project I could have handled.

I'm not even sure I could handle the super glueing either blink.gif

just some comments:

 

you how to say should know what you can do with electronic parts and what better not.

 

beeing self-confident could be a plus.smile.gif

 

i only partly disassembled the amp.

 

always use a brush, pressured air and a vacuum cleaner to remove all and be absolutely sure that there are NO aluminium parts, particles and dust left.

 

i checked everything, charging, channels left right correct, two headphones at the same time, charging while listening, everything works.

 

i think it's a real sonic improvement, better bass definition, texture, better micro detail.

 

at the moment while typing i listen to harmonia mundi - cantors before bach - it sounds absolutely gorgeous.

 

btw - i red my own tube reviews and then played around with some tube combos based on what i wrote - starting some days ago i listen to the

 

telefunken 1u4 df904 mil spec - lorenz dl92 combo

 

right now and the more i listen to that combo i think this will be my second dream set.

no facebook, never! 

 

sure you can post the pictures on facebook that someone made this modification.

 

you can be sure that the new placement of the power jack has no influence on the input as the player output is low ohm (resistance). 

 

i have the feeling that just the opposite is true. the power jack always has power even if no power supply plugged in and the battery has a very small electronic pcb with i think the charger logic on it, so now the power cable and jack can't influence the preamplification stage with for example rf interferences.

 

you should send shikada san an email to get the amp modified in the same way, it's a real improvement.

 

btw, as mentioned by you, i did a in the best sense of the word complete photo documention, will fill half a book, around 50 pictures.

 

edit:

 

just saw that you wrote confusing and not influencing the input.
