Search Engine Hint
Next time you look for a tube using your favorite search engine, enter the type, space and the word pax. (example: M2642-419 pax).
That will bring us up as one of the 1st pages instead of 1000th or something.


The dealer net info comes from catalogs like Newark, Allied, Richardson, MCM , CEI etc.

A small 'u' after the type number indicates used tube.
Clicking on an underlined 'use' or 'try' recommendation will take you to that suggested replacement. Your back button will return you.
