With these quotes and potential problems it is almost more beneficial to just get the Antek trafos and ship them to the Netherlands for the premium price. No fancy box to put on top of the case though... (and no 13/14VAC ones, just 15VAC so more heatsinking for the LV supply)

I'm waiting for two new trafos from Toroidy. If I have problems with it again probably I will try other manufacturers

Measures (no load):

AUDIO GRADE TSA300VA PRI:230V SEC:
> 2x360V & 350mA      386volt/386volt
> 18-0-18V & 600mA   18,63volt/18,63Volt
 
AUDIO GRADE TSA60VA PRI:230V SEC:
> 2x 6,3V & 4,5A  6.83volt/6,83volt

No noises or hum . The measures are... more or less but I'm worrying for HV (a difference of 26volt)

The difference in voltage is only app. 7%. If you look at other transformer specs you'll see that this is perfectly normal for a 300VA toroidal, so it should be absolutely nothing to worry about :)

Thanks for the follow up. Toroidy still a candidate then. Should I run for 13, 14 or 15 VAC secondaries for 12VDC regulated?

Got my boards today. Thank You!

I have posted pics before but here are some more of my build. I noticed these boards have a 12 V for the filaments. The old board did not have it.
