Any kind soul who owns a diagram of the 990 control board?
Trying to modify (yeah I know that may jeopardize waaranty) it to 230V.
Looks like all relevant components on it are 250V or more, no worry about that.
And of curse I'll have to rewire the primary of the little transformer to series operation (luckily it's designed for 115/230V operation).
BEWARE anyone trying the same thing, there's a hidden top layer track under the transformer you'll have to cut just like the top bottom track primary link!
Looks like the two big toroids are sequentially switched on, have to think whether this'll be possible now, since I seried their primaries brown1 - black1 to brwown2 - black 2.
Must think hard how to accomplished this in my situation!
So a diagram would sure be nice!

Maybe some Super Slinger will be so kind and help me out & be assured to my eternal support to your company and the Hideout!

WARNING:
Don't do this yourself unless you're 100% confident you know what you're doing - there's lethal voltages inside!
