I've never had any interest in the mass market. Or consumer stuff.
In a lab, it really does not matter if you reduce the power consumption of
an instrument a factor of two or even ten from the 1970s or 80s levels.
Tube gear, yes.
The TE business is way down because design has left the bench and gone to
'puter modelling... and to China or Korea.
I do use 'puters for design, but it BORES me. If I had to sit in front of
a screen 40 hours per week, I'd quit and go watch TV. I ENJOY working w/
the hardware.
YMMV,
