I am tempted by their attractive price/uF

Hello,
I’m building AJ with 240v transformer single mains winding.
Somebody madea schematic for this, but I don’t find it anymore.
Was it capacitor across live and neutral and only ONE NTS in line?
Thanks

Hi members,
I think I did it.....first adjustments done.....seems to run fine.
I went with adjustment guide from 6L6 on the thread start setting bias to 0,4v and zero dc offset.
Now powered on bias is up over 4,5v settling down to 0,4v.
Highest temp on device just under 65C and 55C heatsink.

But I found another post with adjustments posted by ZenMod that needs to put 10r,100r or 1k for R30.......i still have jumper at R30....should I change?!

Another question......I’m still not sure with the fuses.....I’m running 240v 400va transformer
What fuse value makes sense?!

Thanks
Gregor
