----- oh, but they do in the original when played correctly. Perhaps the 
problem is that Blumlein recorded lateral/vertical, not 45/45, so the signals 
from an ordinary stereo pickup will give nothing sensible. You need to add 
the signals in phase for the lateral and in antiphase for the vertical, when 
you play these records. Possibly the reissue engineers did not know about 
this when making the box. But then, are they worthy of the designation 
'engineer'?

A set of the 78s was pressed in vinyl about 15 years ago, with electronic 
matrixing instructions.

Kind regards,


George
