[RE-wrenches] Fried Classic150?

[bob at midnitesolar.com]

Yes, the 9V is because of the auxiliary power supply that powers 
everything inside. Not just the Classic of course.  Lots of voltages and 
various

power levels required to run these things.

And charcoal inside a Classic refurb !   Hmmm...  You can be sure...   
There  WILL be spankings !
