Is the 6,3V filament derived just from a voltage divider? The values in the schematic don’t add up…
Or is the regulator just for B+?
I see the transformer has a 6,3v winding.

The voltage divider is the reference potential for an elevated heater (AC or DC), the rest is only for B+.
 
Ah, thought I missed something.
So this would be perfect for CJ‘s 6N1P Bass DI, right? If one is ok with AC heaters.
I’m interested. How much would the shipping to Germany cost?
 
Board is only for high voltage.
6.3V for filament is from the transformer only, AC.
Shipping to Germany will be about 9-12 EUR of 1 kit (unfortunately online price calculator doesn't work)

Have not yet tried the PSU but it arrived safely and looks good.
Very nice contact and he even added some little gifts to the package.
