Tavish Design Adagio Owners

Hello 

I know that there must be a few of you out there , since there was a 12 to 14 week waiting period when I had ordered mine and they been made since 2016 .

What tubes are you using ?  Which ones have you tried ?

If you haven't changed your tubes since purchase and you want to try something new
start with the 12AU7 , like I did since it is only one tube , which I have found to have some of the greatest 
influence on the sound .  So far I've tried 3 NOS tubes from the late 50's and the 1 new one , that I am using . 

For the 5751 trio I am currently using 2 new Tung-Sol gold pin cryo treated 5751s in positions 1 and 2 ,
in position 3 I am using a 1959 GE gray long plate 12ax7 .  
For the 12AU7a position I am using a new Genalex Gold Lion gold pin cryo treated tube and 
for the EF86 positions I am using 1972 Tesla EF806s tubes .



This phono pre-amp not only sounds great but is also a whole lot of fun tube rolling !

Thanks Rob, I do like it a lot! The tubes substitutions are based on Scott's recommendations below: 
"In my own personal Adagio I use Sylvania 6267 for the two EF86 in the second stage (6267 was the US designation for the EF86). NOS 6267 are getting hard to find, however.

For the output tube I use a GE 12BH7 in place of the 12AU7/ECC82. It is a larger tube with higher heater current, but the Adagio heater supply has adequate capacity for it."

I am using a Kiseki Purple Heart N.S. which has a .5mv output. The Adagio has plenty of gain for that cart.

That is a highly regarded and praised cartridge , You Lucky Guy .

While I can't afford a cartridge like that I can to try a 12BH7 , thanks .

Something I experienced that I'd like to pass on ,
I had 3 12ax7 GE gray long plate tubes dated within 6 months 1959/60.
I was testing them in the 3rd  position , 1 sounded ok , the 2d one sounded real good but the 3rd one sounded magical !

You might want to try each of your 5751s in the 1st position ,
or go a little further and put  JJs in #2and #3 using a GE in the 1st position rotating the other 2 in and placing the best sounding one in position 1 .
You might find a little more magic .

I'd like to pass on something I experienced with 3 of the same tubes 
dated within 6 months of each other 1959/60 , GE long gray plates ,
2 sounded good and one stood out like magic .
You might want to try rotating your tubes to the 1st position or
go a little further and place JJ tubes in 2 & 3 to help isolate the sound of your GE tube while listening for the magic one .
