I tell you what it is that's putting everybody off, it's that bloody input stage biasing arrangement...

The other thing is that people who know enough to build it have probably read a bunch of stuff here and there, and therefore been anointed in the "received wisdom" regarding:

solid state rectification
enormous no-name PSU caps
6E5p wha? (Can't tube roll that...)

As well as the complexity of the biasing in terms of parts and hassle, it may be a case of "Not invented here" , particularly if its benefits are not theoretically obvious (in addition to its complexity).

Just guessing at the reasons...
