Gary Pimm's Tabor is sensationally good, in either tube or solid state. He uses the same outputs and different interstage's in both. He has not updated his site to reflect any of his usual information, but you might try contacting him to see what sort of help he would provide you for a DIY build.

I know tube amps use a transformer to match the output tube to the spealer such as 5K:8 ohm but what spec do you need for a transistor output stage?

I too have been wondering what you could possibly gain by using a OPT for a SS amp? SS is in no way having problems supplying the required current.

It's 1967, you want a 300W amp.

No high voltage devices available.

Run everything on 40V and use a transformer

I'm with you this far, but it beats me why some still use an OPT ?

I remember JGH writing in Stereophile about a McIntosh with output transformers and giving it a very favourable review.

I guess it would be good for speaker protection if nothing else.
