Has anyone seen the KT-150 in the wild? I know of one amp that is using it but does anyone think it will be a drop in replacement for the KT-120?

Looks like an egg. That would be cute on my Baby Kronzillas if they can indeed be used as drop in replacements.

I saw them at CAF last month in a new Jolida amp in Greg Beron's room. From what I understand, the new KT150s replace an EL34 so they wouldn't replace a KT120 or 6550 unless the amp is able to use all these tubes.

Perhaps Greg could shed more light on the subject.
