yogi Posted November 26, 2007 Report Share Posted November 26, 2007 I have just received my fiddy with Upgrade to AR coated sapphire crystal it seams to have a lot of distortion in the crystal. Is this normal ?? I have done the sapphire crystal water test and compared to my gen sub looks like mineral is there any other way I can test to see if I got what I paid for Thanks Quote Link to comment Share on other sites More sharing options...
Sweattdogg Posted November 26, 2007 Report Share Posted November 26, 2007 (edited) Is the distortion in the crystal or in the way the dial looks when viewed through the crystal? I have sapphire on my fiddy and it creates a heavy distortion of the numbers of the dial when held at angles and especially around the edges. This distortion is consistent with the gen. Besides the water test, I dunno of any other in-home methods to check the crystal. I would think that anything that is AR coated would have started as sapphire.

Sweattdogg Posted November 26, 2007 Report Share Posted November 26, 2007 Sounds normal to me and also consistant with the gen. As far as what the crystall is made of, I would guess if you bought it here on the forum and the seller is reputable, then it will be sapphire. There are devices which I have seen that tell what kind of crystal it is, but I don't know where you would even start to look for one of those.

HauteHippie Posted November 27, 2007 Report Share Posted November 27, 2007 The Fiddy crystals have a large curvature and typically distort the dial around the edges. Quote Link to comment Share on other sites More sharing options...
