Default Lundahl LL1620 SE-OPT : Ultra linear ?

Hi,

I would like to use my Lundahl LL1620 SE output transformers with a 6550 in UL mode.
Is it correct when I connect taps 1/6 to the screen grid I get a 25% UL tap ? (see attachment)
Is this OK or should it be the more common 43% ?

Thanks,
Jim

Yes, the connection you show will give you a 25% tap. Whether you will like the sound of that more than some other tap location I consider a matter for experimentation rather than following someone else's recipe.
