I would pay a small premium to help the designer lower costs. I prefer PCB over P to P.

Needs some work. Looks a little etch-a-sketchy

O.K. here comes the minority report for ZM....

ISKRA has lowest THD in my measurements, a small bit lower than Jensen....

means 0,004% smaller....

because k2 is still lower than the k2 of Jensen. Buzz said this could be sign of the similarity of windings....

k3 is a bit higher than the k3 of Jensen....

so if I increase the k2 to surpass the k3 about 6db I get with the ISKRA a bit more THD than with the Jensen, that may be the reason I find the ISKRA a bit more detailed and less dry.

Here is my first PTP wiring attempt - I know needs improvement

PSU choke filter +/- 24V

Current at R100s 1.48 A

Voltage G -S on R 100s = 1.38V

DC offset approx 5 mV

Will put it in system later this evening unless I hear not to

Thanks everybody

I hope you will like PtP.....!
Do not forget to put an 500R or 1k pot nearby to put it parallel to the upper secondary if you should need some more k2....

May I all ask again....?

The original circuit Nelson gave us had in my build k3 and k2 on the same level,
is this intended or due to my build and parts?
Shouldn't k2 be dominant per se? My second channel even had k3 higher than k2.

I am sure it is similar to the J2, in that all the parametrs matter. Isnt ig the easiest amp to play around with. Have you tried switching the phase of yhe top and bottom secondaries?
