Manley Chinook Owners Tube Rolling

Cords are only a little more overrated than tube rolling. Which is overrated.

Sorry Lew, you are wrong on this one. Or, you're right. Maybe you've not experienced the improvements wrought from alternative tubes. Or maybe it's no big deal to you. Or your gear is so incredible that mere changes in tubes yield no gain. But from my experience, it is night and day.

Hey noromance have you tried these  They look like power cords for no $
Heck maybe try 1 of each Never he
M.ard of them

Tubes of the same type made by different manufacturers do sound different to me. But in my experience differences don’t hold up over time. Then too, same tubes from same maker can sound different from one another; there’s a sample to sample difference. There is no substitute for understanding how the circuit works in the first place. But I admit there are some tubes and makers  I really dislike. In my Steelhead I use Siemens CCa for that one gain section. 

The is a certain amount of variability in tubes made by any manufacturer.
Buying untested NOS tubes is a crap shoot. The most important and noticeable characteristic is noise. The best tubes have to be selected out by testing each individual tube. The only company I know of that does this is RAM Labs here   http://www.tubeaudiostore.com/emission-labs.html
I use the Super Low Noise 6922's in my ARC phono amp and they are way quieter than the stock tubes and I mean Way Quieter. They are also super expensive @ $90. But you can choose Low Noise or Standard tubes. In a phono amp I think SLN tubes are a must. This is a difference you absolutely will hear. They have to test 100 tubes to get one SLN tube.
