post #3406 of 3704

So I think this has been mentioned already here but it seems there's another revision to the power/transformer(?) module in the TUR-06. I met Shikada-san at the Fujiya show this past weekend and he mentioned to me about sending mine back in for the upgrade. (Un?)fortunately he's really busy so he won't be able take mine in till a few months later to do the upgrade.

 

I didn't get to try the difference in SQ to the power module between the old and new so I can't say what difference it makes but I absolutely love Shikada-san's post sales support. A true honest and pleasant man to deal with.

I finally re-read the manual and got the Hugo working at a decent line level with the TU-05b. It's obviously a better DAC than the Meridian Director, but absolutely not 3.5x better. Not that I'm selling my Hugo. Both are great DAC's and perform way above their price/class.

I prefer use it with tur06 even there is noise at the background. tur06 very good at instrument positioning. It fills anything that Roxanne lack off... Roxanne bass + the way tur06 render the space = bass to die for.. :D imo this is the tube sound that no solid amp can provides..

Thanks. What tubes are you using in the TUR-06 ?

I am still using bonitomio telefunken diamond base tubes.

a short "intermezzo":

 

after a long time of searching i found very small transformers that can be used as output transformers for my "mini" tu-05 with subminiature tubes so now a really small "mini" tu-05 is possible:

 

 

i have connected them to the tu-05 and must say that they sound much better than i had expected, slightly less precise, slightly harder, punchy, but very spacious, they do not run into saturation, obviously not enough iron for deep bass, but some equalization helps.

 

 

These transformers are very small torroidal 1.6w power transformers (only 4cm x 4 cm x 1.8cm), of course not SE output transformers, but the DC current of the subminiature tubes is very small, it's easy to provide and automated switch mechanism to change the polarity of the tube outputs for example whenever turning the mini amp on to prevent the cores from getting magnetized.

Hi bmichels,

congrats on your latest exotic acquisition!

What types of tubes can this unit test?

Can you give me some idea as to what parameters this can test each tube?

post #3416 of 3704

Industrious work as always GG.

Can you clarify for me if these transformers are intended to be used in your "regular" tu-05, your desktop tu-05 or another project "mini tu-05" that will be similar to the tu-06?

As always great work and please keep it up :)

post #3417 of 3704

it´s another project for an as small as possible SET tube amp based on the tu-05 design.

Sorry If I confused you, but I do NOT own this tube tester. I was just reporting this device being displayed at the Munich's High-End AUDIO Show ( I did NOT attended it myself)

That information is not yet available, but the tester will be able to test 12 different types of double triodes and based on the picture, all the typical pentodes will be included aswell. This unit should at least be able to give data from conductance, anode current and gas. Otherwise it will be a waste of time and money, as it's price will be around 800 euros in europe.

 

Parameters in this testers are pre set, so you can't adjust them yourself. Tsakiridis will add more types to this tester as time goes by, and they will be added to the tester by updating it.
