post #1501 of 3704

will try to replace it with this neutrik 6.3 mm one:

 

post #1502 of 3704
No those look great. I think one of the other members has that on his amp. Of course I cannot do this mod (even if I would dare try) as mine is a combined switch.

So happy I can now directly plug my HP cable in though I would recommend the Cardas adaptor as from my initial listening it is indeed transparent. I can hear no sonic difference with it in or out of the signal path.

GG. Could you do a photo tutorial of swapping over the socket, I would love to see that!

I was wondering where you obtain the Odin I/C? I am surprised the person making the cable for you will be using Pailics jacks on an Odin wire.

 

My friend has made a diy mini i/c from his stripped Odin Interconnect which I have heard, and it sounds delightful, especially the trebles. I am trying to ask him to make me onewink_face.gif

 

Cheers

Hmmm... it's pretty worrisome news.

 

I would be delightful if you gentlemen might alarm this issue to Shikada San, as I might also give him a buzz regarding this matter.

Thanks.

post #1507 of 3704

Yes.

 

GG, thank you for sharing. And thank you very much for shipping the tube cleaning kits, what a treat!

 

But the loosening output jack over time is worrisome, for sure. I am looking in to a male to female adapter cable so that I don't have to use the output jack so much...which I should not have to do, for an amp at this level of build, sound quality, and price.

 

Edit: as of now, both of my jacks are rock solid, I'm only paranoid, as I also have the separate power switch.

I have to be honest. I have not had an issue with mine since the initial problem and it was a very easy fix. However, I am careful with it.
WC, I can heartily recommend the Cardas adaptor. I have one and having now tried the amp with my HP directly in instead of with the adaptor I can say that the Cardas adaptor seems to have no sonic effect which is ideal!

I do think though that in the end Shikada san should just put a good quality 6.3mm socket in the amp.
post #1509 of 3704

I've sent a message to Shikada San regarding this issue on the headphone jack.

Asking him to take a second look on it, although I believe currently he's using the best parts that he might find.

Thank GG for sending the cleaning kits. I should have them just in time for when I come back friday from Moroco :-)

As for the headphone jack, i may try another route: to replace the 1/8 jack by a mini-XLR plug. this will look superbe and will be 100% saffer ( I don't have the " long case", so 1/4 jack Will not fit ).

It Will look like my TU-05 is à Balanced Amp ! :-)))

What do you think.

Have just taken delivery of one of the last pairs of DT48s (25 Ohms). I have only had a chance to test them with an older Marantz integrated, and they're not run in yet, but first impressions are extremely promising. The frequency extremes are curtailed and the soundstage is compact, but the degree of clarity and the quality of the midrange are absolutely astounding (reminiscent of electrostatics). I will try them with an OTL valve amplifier when I get back to China...

this is not the first problem i had with the 3.5mm jacks, not only with the tu-05. i know that mini xlr is an excellent choice, but on the other hand i have started to replace the 3,5mm jacks with 6.3mm jacks as standard for my headphones as both my colorfly c4 and the Cayin ha-1a have this output and at least the 6.3mm connectors are much better than the 3.5mm ones.

 

P.S. and not to forget - did you ever try to solder a thick headphone cable and a mini xlr jack ??

GG, I have been told by my local Hifi store that 3.5mm jacks are notorious for failing or having issues. I think the answer really is to forget about any pretence of this being a portable amp and simply add a good quality 6.3mm socket. It is easy enough to use a mini adaptor then for the headphone cable.

new tubes arrived:

 

radiotechnique df91:

 

 

 

tesla 1F34 (similar to df96, but heater needs 1.2 volt 30 mA):

 

 

 

tomorrow i will get the 1L33, hope they sound exceptional, they are similar to dl92, but need only half the current for the heater.

 

df91 / dl92  (2* 50mA + 2* 100 mA) = 300 mA for heaters

df96 / 1L33 (2* 25 mA + 2* 50 mA)  = 150 mA for heaters

the problem is not especially related to the quality of the jack used but a general weakness of the 3.5mm design and also the connector. i one or two times plugged a interconnect with a slightly crooked and bent connector in the tu-05's jack, and that's just enough to damage a 3.5mm jack.
