I've been working on organizing all tube data for testing tubes with an EICO 635 for a couple of days. Page is gonna be available under 'Tube/Valve' - 'Tube Testers' - 'EICO 635' left menu, at the main home page.
I just finished the page for EICO 635 tube tester. Although I have reviewed all data, I'm not sure if they are all OK.
So use it at your own risk.
