DAC interstage-trafo output (PP-SE)
About 6n6 tube.
One variant for example:
The battery is 1.5V ,
r(cathode)= 250 Ohm.
L=0.25*r/Fr
L=0.25*(250 Ohm/0.25) Herz=250 Henry.
This trafo with Cobalt (Mu=120000) core have this HenrY.
The Ferum trafos is near 180-200, but it's real to get 250 Hy too.
I havetThe Cobalt and Fe cores becouse I work with a factory which make make this kind steel.It's a big fild for experiments.
I love bass and ultra-minimal faze distortions.And I try to make more low bass spec as I may.
If 6p9 - I like this tube, the Io=70ma with 2*1.5V (-3V) acumulator. r(cathode) = 75 Ohm.Second primary is antifaze coil.
L=0.25*(75/0.25)=37.5 Henry.
this tube I love too/ i like high Slew Rate (because delta I = 80 ma)
At the early picters is nano-crystal (amorph) Ferum with Mu=90000, it's like the Perm steel and Mu may be more, but max inductance higher of this core and data like simply Fe.
The high frequency will be more than 200kHz.
Now I have a plan to raze the toroid core by lazer.And it's will be Ferum and Cobalt. It's will be SE trafos. But the steel with air grap have less indictivity. I will tell after experiment.
For 6n6 and 20Hz.Inductivity must be 1.7 Henry.
For 10 Hz= 6.25
For 5 Hz = 12.5
For 1 Hz = 62 Henry...(This calculations I love more)...

For Pepe
Thank you Pepe.
About rectifier tubes.
I think that diedes good for sound too.
I think it's better to taste to make the tube stab?
you may use the second trafo for make higher the Voltage. The tube is make the delay and make low output impedance.
But if you wish to use the rec tubes - it's may berec tube for plus out and two diodes for minus.
The chokes is economy of energy and i will show the picture too.
I will be make sectioned choke for CLC filter. I like LC, the sound is softly - better faze parameters, but it's no economy.
i have a plan to make classical steel and nana-cristal razed (air grap) . The amorph core is will have super-clear sound. all this i will show after make.

Interstage trafo 2K-2K (1:1)
Primary 2K at 20Hz
for tubes like 6E5P and other in a picture below
-3 db 10Hz - 45 kHz
Core S=12 sm2
w1-w2=2000+2000 d=0.22 mm R=150 Ohm (it better than Tango NC20 where R=400 Ohm)
8 sections
Io (DC) =80 ma, I max = 160 ma
