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

Is it possible to for kt88/7AC base tubes with an adapter to be plug in a 6A3 SE amp?
Realdeal I was thinking about this thread and was wondering what design parameters are you considering to implement with this attempt?
Found the 10-19 post below on the "Designer Hall of Fame" thread started in '08. Now if we only knew OV, might have a clue what's going on with this line of inquiry.

OV,who designed tube rectified OTL,using DHT tube as an OPT or any of the 7ac based tubes.Make it possible for kt66/88 or any 7ac based tube directly plugged into a 4 pin socket of a 6A3 single ended amp without amplifier mod.

Thanks, Ghosthouse. Perhaps in addition to clarifying who OV is, Realdeal can provide a link to detailed information about that amplifier. I find it hard to imagine, to put it mildly, that a practical audio power amplifier using a single-ended 6A3 as its output tube could be implemented as an OTL (i.e., without an output transformer).

Charles, Rleff, Onhwy61, thanks also :-)

Rleff,Without proper electronic background,you can't tell Al is well verse in electronics,none from his remarks that I can pick up that he is,Ralph?Yes.
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.
