I just pulled my second 12X for testing. The diode is still in the heat sink. I will remove it in a less destructive manner. "Squeeze-squeeze" certainly works. It is just not as fast as "snip-snip."
The first 12X (and another LG8X) sled is already on its way to you. I can put this little heat sink into a regular envelope. However, did you want the second 12X sled as well? That would require a "package." Also, it is still in the drive. It is simple to harvest the diodes from these last two Pioneer drives without even removing the sled from the drive.
Squeeze-squeeze is not fast? I really should make a video. Squeeze-squeeze takes three seconds per diode!
But then again, if you are used to Snip-snip, i guess it really is faster for you...
In any case, i have a Pioneer 8x sled here...
You just informed me that you already sent a Pioneer 12x sled to me... All i need now is the non-destroyed heatsink, to put a diode in, reinsert the heatsink into the sled, and test sled efficiency using the same diode first in one sled and then in the other...
I'm hoping the heatsink will make alignment easier. Otherwise, the results of the comparison could be quite meaningless..
I don't need a second 12x sled tho....
Dave, the most helpful thing now would be a good plot. Of both diodes.. Doesn't even have to go high, since their power increases linearly anyway.. But you really do need a driver that could go lower in current than 58mA..
You could remove a resistor and pot from that driver, and wire a big pot with a large knob in their place...
Or, you know what... Just take a photo of the driver you are using, showing the resistors, and tell me the value of the pot, and i'll tell you what to change, so you can actually check Ith...
I have a feeling that all it will take is removing a resistor in parallel with your pot, and you'll suddenly be able to go lower and measure Ith (but it won't go as high as before anymore, until you replace the parallel resistor again)....
