If you arrived here following an auction purchase, please send me an email. The following information is free.

Stage3
Using the minimum value on this guide will give you 550ma. This will shorten the life-time of the MCA but by how much - I'm not sure but the extra brightness is worth it I think.
As long as you obey a strict duty cycle and don't let the laser get too warm - you should be ok - I have looked at specification sheets from Sony that say the diodes max current is 500ma - so it is not being 'overdriven' too far here.
Here's the top of the set:
Resistor marked yellow - take out and swap for a value 220 ohm or larger (220 is the minimum - any lower and you risk the diode). This resistor limits the current for the maximum setting of the pot - you'll notice another resistor on the other side - that controls the minimum setting of the pot.
And now the bottom of the set:
Again resistor marked yellow - take out and swap for 3.3 k ohm (3300 ohm). This resistor is necessary to stop all them extra 'ma' that you are now giving the diode from flowing back into the circuit again and shortening its life.
And that’s it! /ubbthreads/images/graemlins/cool.gif
