Good news!
Freya+ with JJ stock tubes sound decent!
Thus you can try out Freya and Jot R without Nos tube.
Schitt offer generous 15 days return with some stocking fee.
Using socket saver, I had done some tube rolling.
All quad Sylvania GTB made in 1955 sounds neutral with somewhat gentle treble.
I had paid 200$ for quad from reliable Ebay dealer.
RCA gray tube in gain stage and Syl GTB in buffer stage give warm and lush sound.
Sylvania vt 231 which had been my favorite for last years in Line Magnetic 508 int amp give more transparent and details when used in gain stage.
Out of curiosity I had gone to all quad stock tubes.
I had run demagnetizaiton tracks twice ( 6min each) and started listening to Eva Cassidy's "Autumn Leaves, Songbird" , "The trinity Ssession" by Cowboy Junky and Trittico by Fennel for classical music.
I had expected somewhat etched or bright sound out of JJ stock tubes.
Wow Freya with stock JJ tube sounds very dynamic with good details.
Compared with Nos tubes, it is slightly veiled and lacking refinement, but it is still quite listenable.
It will improve after break in.
Users of Sr1a and Jot R can try out Freya with stock tube.
If you like the combination of Freya and Jot R, then you may buy Nos tube depending on your taste.
Syl GTB sounds neutral, Syl vt231 sounds detailed with excellent transparency while RCA gray tube sounds warm and lush.
Have fun everybody.
I am still waiting for delivery of "Bad boy " version of Syl on Monday.
I will update on it next week.
