That's not what you have got. It's what you think you have got.
You have 30VDC out (+/-15VDC).
You have a wall wart transformer with poor load regulation. I'm guessing
it's
about 15VAC you have coming out of your wall wart. I also suspect the
original
design is relying on this to work.
Try taking some measurements rather than quoting the info that's printed
on it.
Mark said he had 4 diodes in the rectifier, that's not a normal doubler.
or rather that's two doublers one going up and one going down.

I don't think it could be rightly described as a "charge pump" device at
all.
** Oh yes it can.
Apparently (because I had to look it up) Charge Pump devices work by
electronically switching the polarity of the capacitors. IE "the
capacitor is disconnected from the original charging voltage and
reconnected with its negative terminal to the original positive charging
voltage".
** Exactly what the diodes do when the AC polarity changes.
Yes, it is a pair of half-wave rectifiers which DOUBLE the voltage. 9
VAC
in and +/-15 VDC out AFTER regulation.
** Totally impossible bollocks !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
9 volts AC = 12 volts DC *peak* after rectification and filtering."
There is no escape.

This troll doesn't have a clue about even basic electronics. No point
trying to explain anything to him.
All he does is make a (bigger) fool of himself by automatically
contradicting whatever you say, claiming that he knows more than you do
and claiming to have you on his hook, to provoke more responses. Sorta
like the Monty Python 'Argument' sketch.
He's a stock-standard newsgroup troll. He doesn't have a life so he
gets on here for recreation and entertainment.

Get back under your bridge, irrelevant clueless troll.Oh surprise, surprise! ..and what do we have here?..
Why, it's Philthy and his #1 offsider, Sponge-Bob!
Here to 'save the day' are we Bob? ..earning brownie points with the
'uno-supremo' are we?
..or shall I refer to him, in his official position in the community of
'Phil-O-phile', as 'Das Führer'
..those 'points' must be very brown. Just like your mouth.

Which description method would that be? "Charge Pump" or "Voltage
Multipliers".
These devices are commonly classed as Voltage Multipliers.

Yeah, right. Or to paraphrase your own comments:
"Hey, just because we behaved like arrogant cunts, don't expect any
better treatment elsewhere"
which is roughly to say: "Usenet is our life, and we can follow you
anywhere"
Go and annoy some other group with your babble, troll. We're tired of
you being here.

Meeeeow! I can just picture you, sitting in Pilthy's lap.
Will you chase a ball of wool for him as well?

Troll (Internet)
From Wikipedia, the free encyclopedia
"In Internet terminology, a troll is someone who intentionally posts
derogatory or otherwise inflammatory messages about sensitive topics in an
established online community such as an online discussion forum to bait
users into responding."
Get back under your bridge, troll.
FoolThat will serve as an almost functionally perfect description of 'Das
Führer' of 'Phil-O-phile'.
..but I would have added a few adjectives like "embarrassingly wrong"

What was wrong with either of these suggestions?
a) Buy another UPS (on Ebay for around $30) and then just step-down the
voltage using my pre-existing wall-wart transformer. If 240 VAC goes in,
something CLOSE to 9 VAC should come out and everything is happy,
..maybe.
good luck finding an online, sine wave, UPS for that price.
A $30 UPS is likely to be modified square wave, and offline, and it'll be
exactly useless for your purpose.

I thought of telling him that, but I knew he'd disagree because it
wasn't what he wanted to hear, so I didn't.
