I won a couple of NDB7A75 diodes from Newgazer on ebay that were listed as " NEW " although they do have tin pins, but that's understandable as they would be pulls AFAIK.
The divergence is good like an 05 diode but the interesting part is the color is not 445nm, I am not using a spectrometer but I have seen many 445nm beams and when placing this next to a 7875 the color difference is apparent.
This 7A75 diode is 9mm of course and has the can/window, what I want to know is did any of the 7A75 diodes put out 450-455nm ?
If not could this possibly be a 05 diode with GBall removed and a can/window put in it's place ?
I have another one on the way and I will look at the can where it's attached to the backing plate with my microscope, unless there were any 7A75 diodes that put out 450-455nm, but I thought they were all 445nm.
Does anyone know if the original 7A75/7K75 diodes were 445nm, I never bought them when they were plentiful, I jumped right to the NUBM44 from the NDB7875.
