Hi Mike
i've always read your posts .
My Cat is reference from the 80's,i know him like my wife and i
have rolled several tubes in it
To begin with i have to say that the most important positions
are v6/v7(12au7):i've tried philips,teles,raytheon,but i've
always turned back to Rft ,but it's not that simple ,because
you have to find the right ones ;i reject overall 10 -12
to find the right couple (i use a B&k 747 but it is not
sufficient )
Last time i left 2 tung-sol ,following your advise too,
and they are not so bad .
For 6922:v1 v2 v5>sovtech ,Eh(but they span from orrible to
marvelous ,again it'a hard work to find the right
ones )
v10 >always used ecc 88:old philips ,not the frame
getter,but the one marked GAdelta Z1F(they
can be remarked Geb,Tungsram or Philips);
or Amperex (holland)
sometimes i found ecc88 Vokshod did the trick
For 12ax7:Ei,JJecc83s(if you find the right ones very very
nice )
I've always tried to preserve the carachter K Stevens gave to
this pre,smooth and precise(convergence ).
Now i'm in love with c-j 17ls ,but i've always turned back to my
old lovers.
Ciao
