I did them all at once, since I really didn't feel like doing one or 2 tubes at a time. I also opted for the upgraded transformers when I ordered the Adagio. Scott said that they improved the bass response among other things. Yeah, I will likely not go for the tube-regulated power supply either. That's a LOT of money!

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 !
