Yes, the idea is to make a page about it and how to lower the output voltage
and how to get more power from it.
As A part of it I draw a schematic of it, which I'd like to publish to with
calcualtions.
The schematic is taken directly from the LM317's datasheet's examples.

Still, I cannot figure the resistors out. Seems to be some custom designed
resistor pack. Will check tonight. If anyone knows please come forward.

(...) Agreed. Ask them! Typically, though, publishing things that you reverse engineer is a lot less likely to cause trouble than releasing information that you obtained from the source. Presumably you've reverse engineered the controller? (24 years ago, 4-Jul-02, to lugnet.trains)
