Thanks a ton for comments! The board as is, is stable and cool and apparently noise free, and has run 1 12AX7 at 300 volts with a 9v supply in the field for long periods of time in a audio application. Of course 1 12AX7 draws very little current. I dont know why RSense was left off but thats the next thing im going to try. And I will find someone with a bench capable of doing a proper high frequency oscillation test.
In the meantime I going to try a couple of Taylor edge boards for this new project, assuming the switching freq. is high enough for an audio application. Thanks again, if you folks think of anything else to check please post! :) Bob On Thursday, April 16, 2015 at 2:24:53 PM UTC-4, taylorjpt wrote: > > Here's a PDF from 2004 on probe connections: > http://www.tayloredge.com/reference/Electronics/TestBench/ScopeGrounding.pdf > > Especially when testing power supplies the ground wire acts as a single > turn magnetic pickup. > -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
