Oh Mighty Choky 
For NTC board @230V is it necessary (like in Papa's schematic) to have 2X115V primaries or can I go for single 230V?
So long and thanks for all the PCBs

which means - one NTC small pcb is covering two Donuts, if they;re in same case

Mostly decadence than civilization...
Yes, same case, two donuts.
Thanks, oh mighty Zen, I'll put a Disater Area album in your honour, waiting for some black starship diving into the Sun 😀

While filling the cart at Mouser, I've noticed that 120 Ω resistors are missing from the package/order list (post #15) and Zener diodes should be 5.6 V instead of 6.6 V.
Oh Mighty Zenmod!
I'm close to getting the LuDEF ready to power on and do trimpot adjustments.
Is there any recommended initial setting for the trimpots?
Thanks
Bruce

Low Output
Mighty Zenmod -
I powered up slowly with a variac and successfully got the trimpots
adjusted without any drama. All settings adjusted as expected.
But with speakers connected the audio output is extremely low on both channels.
I'm using an EDCOR PC600/600.
Any ideas?
Thanks
Bruce
