Sukhbinder Posted September 27, 2009 Report Share Posted September 27, 2009 We use a CRT setup as a part of our experiment for our students to calculate the e/m ratio of the electron. The experiment is usually referred to as finding e/m ratio using magnetic focusing. The supply to the CRT seems to have some problems and the setup is quite old and no circuit diagrams included. the setup uses a HITACHI oscilloscope CRT. the only thing mentioned on the CRT is TYPE no:95CB31. I was planning to repair the setup but need the CRT pinouts and specs like the heater voltage, current.Any one having any idea about this. could not find any thing on google. ;) Quote Link to comment Share on other sites More sharing options...

hotwaterwizard Posted September 30, 2009 Report Share Posted September 30, 2009 The model number would be helpful. Maybe these links will be helpful to you.http://www.repairfaq.org/sam/crtfaq.htmhttp://www.electronixandmore.com/project/7.htmlhttp://www.tone-lizard.com/Oscilloscopes.htm Quote Link to comment Share on other sites More sharing options...
