I'm working on a SE KT88 amplifier design and wanted to get the groups thoughts on splitting the B+ feed after the first cap (following the 5U4G or similar) into a choke per channel.
I've seen some high end designs that deploy such a topology but its typically a full LC filter followed by two additional LC filters, one per channel.
My main reason for considering this approach is to keep the choke size to 100ma per channel thus smaller in size and being able to fit them under the chassis. I'm trying to avoid an above chassis choke, more for cosmetics of the design.
I know it would be a slightly more complex design but that's acceptable to me.
Thoughts? Pros/Cons?
Thanks,
Mark
