My bad, many synth displays use an inverter, some things have a 
transformer. Multipliers though, usually use pulsed DC. On simple boxes 
though, wrong polarity can take out the rectifier diodes if the DC supply 
has the output amps to do it. Bottom line, if the first things the wires 
go to are diodes, good to go. Transformers first, no good. Other 
components, do your homework.

My personal solution, if it were my gear, would be, go to Goodwill/St 
Vinny's and look through the wall wart basket. I get a LOT of my PSUs that 
way. Watch the amp output though. More is good, less, not so good.

 Not always true, in
 several pedals that use AC adapters, there are voltage
 multipliers to allow +/-15Vdc to be created from a 9Vac
 input.

 AC boxes will run on
 DC, but you have to be careful of polarity. You need the +
 DC to go in on the same conductor that moves forward through
 the rectifier diodes

 Hi folks,
 I
 just got a Boomerang III and all of a sudden I have power
 supply problems.
 
 I'm using the following:
 TC
 Helicon Harmony G which requires 12vdc,
 BBE
 acoustimax pre/di which requires 12v a/c, boomerang III
 which
 seems to require 9v
 a/c
 miscellaneous boss style effects which
 require 9v dc.
 
 Mike at
 Boomerang said that the rang might run on 9v dc but
 the tips
 for my 9v multi power
 supply won't fit the rang.
 
 so, does anyone have suggestions for this
 complicated power
 setup?
 
 ]thanks!
 Rusty
