good to see that this thread is still alive.

After many many years, I still use my TU-05. :)

So I pulled out my TUR-06 recently 'cos someone reminded me that I had it. I've actually not listened to my TUR-06 in quite a long while. To my surprise this was actually able to drive the Hifiman Susvara and at pretty decent volumes for most albums. It doesn't sound constraint nor stressed in driving these inefficient headphones. I'm glad to be able to listen to tubes with the Susvara.

Just ordered a TUR-06. Now the wait begins. Any new/old owners here that can share impressions? Also what tubes are the best for this beautiful amp?
I wrote a review a=on the TUR-06 a good 7 yrs back?

The maker recommended Fujitsu Ten which is quite difficult to find, however they do have a lovely sublime sound. Note that tubes can get microphonic, so just setting expectations in advance.

I did not tried changing Caps or resistors. May be I should try new caps IF it can fit inside the case which is already VERY crowded.

Main change for better SQ was by upgrading the 2 transformers: More clarity & black background. I could not hear any sound improvement with the other changes.




Implementation of the XLR was for convenience to use my Balanced TH900 without adapter.




and of course I has much fun with ... tube rolling

(left case=Voltage tubes; Right case=Power tubes)


Holy cow!!! Your stacks of tubes is hurting my pocket LOL!!!
