Ok, however, I'm at work today (I'm the "facilities mgr." for a major art museum in the midwest (S.E. Wisconsin, USA)) I just completed the 1st voltage regulator mod( may have a problem here, thought I had a ver. 0.40 board, have a 0.41 board and used a LM317T instead of a LM338T, lets see what happens), completed the ZIF socket wiring mods, am now looking at the remainder of the vtt mods (this guy must have had WAY better than 20/20 vision or one hell of a set of magnifiers!), I can hardley see the components and their connections (see http://geta.yoh-tec.com/bp6/eng_analisys.htm
). Got the LM338T in place (stabilization of Vcc 2.5), now I'm looking at the "improvement of the load regulation", XR14 and R117 modifications).
I know he says more work is needed (ver 0.41), however, at this point I'm going to give it a try.
