Tubes have always been proprietary parts. OK, you HP
200C has say a 6SN7 in it. Which manufacturer's 6SN7 is
the right one to use?

Uh..!? Tubes from different manufacturers are
_massively_ better matched than any two transistors or
ICs from the _same batch_!

Thanks for permission to summarily dismiss any and all posts on
rec.audio.tubes mentioning equipment sonics dependent on brand of tube used.

As far as matching of SS parts goes, in practice parts matching is not the
issue for SS that it was for tubes. This is especially true of ICs.
