Is it possible to adapt kt88 to a 6A3 single ended

A word to the wise is sufficient.

Hi Realdeal,
Al's very thorough and thoughtful response is based purely on technical considerations. I feel he is giving you very wise advice, if you want to proceed with this experiment of course you are free to do so. In my opinion these two tubes are about as different as one could imagine. If you do decide to continue this experiment let us all know how it turns out. The analogy would be comparing a Harley Davidson motorcycle to a Dodge Caravan minivan, they're just simply different.
Best of luck,
Charles,

Hi Realdeal,
Could you point out Al's lack of technical acumen based on his reply explanations? I would say his comments have been very factual regarding the differences between the 2 output tubes under discussion. Where did Al go wrong? Thanks.
Charles,

You didn't answer my question. Any how, if you do proceed with this amplifier project, let us know your result.
Charles,
