Thanks Steve. The amp actually drives the galvo just fine with the led out. What would be the effect if one of the components was out?

You are using Bonetti's defense against me, ah?
I thought it fitting, considering the rocky terrain.
If you connect +/-24V correct 2 LED all bright.when connect reversal the 7815 or 7915 will broken.
Normal circumstances 7815 and 7915 almsot no damage.
Repair the driver real a waste of time work and hard work,unless some physics damage you can see.
Hi Jian can we order directly from you ?
Jian these boards were shipped to Pangolin and Bill Benner modified them to work with the 506 scanners. So it would be worth repairing as it wouldn't just be a straight swap.

Still check the regulated voltages from the two regulators. The LEDs run off the regulated power thru a current limiting resistor. So if the amp is working, you may have just lost the Led to reverse voltage or something similar.
You say your still scanning.
If however one of the regulators is blown or shorted on, you may exceed the rated voltage of the TL084 opamps, in which means eventually something else may die.

Mach Mini has been shelved
C506 will begin shipping with Mach DSP shortly- identical to Saturn configuration with a few resistor and capacitor changes - perhaps end of march. Orders are already beginning to stack up, waiting on one more component before it is (finally) a full turnkey solution.
Will also be stocking Kvant and Laser Fantasy amps for those needing an analog solution, although the pricing will be about the same...

suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.
