Re: New DX Red 200
Very nice to see some pictures, also of the insides!
It actually looks well built with a good thermal connection from diode to case.
By the looks of it, the diode would be fairly easy to replace if need be, although i'm not totally sure about that 'collar' of sorts between the diode and circuit board.
Also, the driver doesnt look half bad. I cant tell the chip numbers from the pic, but the topology hints a system with an opamp, 1.25v reference and sense resistor (the big one). This would mean plain old linear regulation, just a current source. The transistor you can see in the 2nd picture (near the diode on top) will probably get fairly warm in typical operation.
I'll assume the pot actually works on this one, and would allow to adjust for a different diode if you wanted to.
Next the spots from DX vs Sony
They look pretty much identical, though its always hard to tell from a picture. What current is that sony running at, and would you say the are equally powerful?
