Thanks for all of the replies so far. As always, I'm very grateful to  
all of the kind folks on the list and I'm learning a lot! Thanks for  
your collective tolerance with my newbie-ness. :-)

O.k... so, just to confirm that I have my facts straight:

I could purchase an regulated bipolar supply such as http:// 
tinyurl.com/yt67t9 or http://tinyurl.com/2238oa. The advantages are  
that I can get it cheap with no building work on my part, it keeps  
high voltages out of the case, and it would successfully power the  
MFOS sequencer. The big disadvantage is that it's a sealed case, so I  
can't trim the voltage output manually.

Is that correct?

Thanks for the help, guys!
