I am trying to make a Quad II OPT SPICE Model, and I have readed the Ayumi article of Quad II.
1 QUAD II circuit

here is the circuit

And I found some information here about
QUAD II Valve Power Amplifier Information
Prim turns of XY=YZ=L1+L3+L5=L9+L11+L14=477*3=1431
NFB turns of UV=VW=L7a=L7b=159
Sec turns L2=L4=L6=L8=L10=L12=51
PQ is 0~4(NFB)
the inductance setting of each part of Auymi's SPICE model seems not maching the turns here

You misunderstood my post, I was merely showing that the inductance and the resistance are equal for the two halves of the KNF winding.
So if I want use the model, I need to add some code in it? could you help me with it?
Since there is no symbol of Quad II OPT in Auymi's web. In order to use his SPICE Model I have made a symbol myself.
and I tried to map the pins of Symbol with SPICE Model
but there is some pins that I can not find in SPICE code, like Pin8 to Pin13
further more there are some numbers(Marked in red) in SPICE code that I have no ideal what are they meaning for?
for example, in the following code
* Primary inductance (p-p 3000ohm 11H)
L11 P1 11 2.75H
L12 12 P2 2.75H
It seems that the number 11 refers to B1 and number 12 refers to B2
but in the next following code
*Primary DC resistance
R11 11 B1 100
R12 B2 12 100
It seems that 11 refers to P1 and 12 refers to P2
It is conflicting with each other

You do not need to have pins for the internal connections, such as 31, 21, etc. The symbol’s pin names should correspond to the names used in the model (that’s the easiest way).
Could you give more detail for how to use this in ltspice? I tried this model with my symbol in ltspice, but can not solve the error.
Rename the attached file to "OPT_PP_KNF.asy" and put it in the sym directory.
Thanks a lot for your symbol
I have made a test schematic to test it, but there is still error
Here is my schematic file
