JLC pcb? They do that. You can order it without order number, or specify an invisible place to put it, by placing JLCJLCJLC i think on the gerber. jlc order number

so ugly ...

how do they compare in regards to inductance, leakage inductance and dcr?
What voltage do you measure distortion with? Do you have a second marinair to compare to? Who knows how different 2 marinairs would be to themselves?

With 50 percent permalloy i can achieve maximum 27 H on primary.
With 80 percent Permalloy I can acieve 50-70 H on single primary.
Now all look better...sound is already great.

Still missing brass construction inside, I hope this week will come..
But is hard to resist to put all in box...just to feel weight in hand ...I think I'm addicted.
