Yes, holmimpusle for example will show you the thing immediatelyI was surprised when I installed some truextent diaphragm to see that they also follow the "old" reversed logic, whereas their doc tell the opposite!
http://materion.com/~/media/Files/PD...nDiaphragm.pdfThe "+" on their diaphragm is in fact a "-", so the doc should read "positive voltage on
- terminal moves diaphragms towards phase plug"...This is good for compatibility with older diaphragms that these are supposed to replace, but I wish their doc at least tell the truth, as I had to reinstall my diaphragms...
