Tube kit for Nagra PL-L?


Nagra recommends that users purchase a "tube kit" from them as tube replacement. This at a price of a couple hundreds of $. What is so special about these tubes? Aren't these Sovtek tubes that are easily available off the shelves?

Any one made any comparison with these tubes?

Jfreck - I've tried and permutated with most of the acclaimed tubes out there and yes you win some but lose some.... After one big big cycle, I landed back to the stock tubes.... Quite a joke right?
