Amazing machines and an incredible amount of hand work.

The 300B tubes are neat to see being made. The monster tubes are really something as well.

Amazingly Western Electric 300B tubes are in high demand because
precisely of the care and quality control involved in their manufacture.

Today a matched pair still avaialable at tubedepot for a mere
$9995.00 affordable price…gulp…

Though apparently Western Electric has risen fromthe ashes of extinction to
production again in Georgia…
