I've found a forthcoming power amplifier that I may be interested in, but
the only specs available at present are that it does 500W into 8 ohms
bridged for mono, and 230W per channel into 4 ohms.

What would be its likely stereo output into 8 ohms?

Those numbers don't quite stack up, but you will get something like
120W per channel - perhaps a bit more.

Sounds fine to me.

It should be 125W per chan - and 230W into 4R indicates that it
propably has a good power supply as well. What it does not show
however is the conditions under which the power measurements were
taken, or the current driving capability of the outputs, so one
channel into 8R might actually do rather more than 125W.

The blurb says it as a 'high current' toroidal transformer.

I think that sort of power is probably well beyond what I need, which, I
suspect, is a good thing. I'll reserve judgement until the tech specs
appear, however.

**A meaningless specification. What you SHOULD be told is that the
transformer IS (say) 800VA @ 5% regulation, or something similar.

It's not a specification, it's part of the blurb. The amp hasn't come out
yet, and the spec hasn't been published.

**Then it's not an amp at all, is it?

In computer parlance, it is vapourware.

Points:

*No one knows if the amp will exist.
*No one knows if the amp will actually meet it's claimed specifications.
*No one knows if it will demonstrate a 98% failure rate, within the first 3
months. And, before you get your knickers in a twist, I am a service agent
for several, large, multinational audio companies. One of those (highly
respected) companies, when asked by me, provided some data which showed a
67% failure rate of one of their products (within the warranty period)! That
company has a good deal more respect within the audio industry than
Behringer does, BTW.
*I am more than passingly familiar with Alesis amplifiers. I am told that
Alesis amps are identical to Behringer products. Alesis amps are cheap,
unable to meet their rated power output without external cooling and
unreliable. Be aware that I am operating under the assumption that what I
was told is correct.
*Behringer amps are not highly regarded in the professional music industry
(I know: I spoke with a few Behringer retailers yesterday, about a Behringer
crossover, I am purchasing. We also discussed mixers and amps.). Apparently,
their reliability is somewhat below average. Apparently, their mixers and
crossovers are pretty decent.
*There is no such thing as a free lunch.

Likely to be about 130 watts/channel into 8 ohms, but that alone
doesn't make it a good amplifier...................

Didn't say it did. :-)

It's another Behringer jobbie. Although I have little to go on, other than
other people's opinions of their kit, and my experience of the active
crossover, I'm gravitating towards the idea that their stuff might just be
rather good.

No techy specs as yet, but here's the spiel from their web site (note that
it isn't available yet, so this is essentially marketing blurb)...

---------------------------------------------------
Professional 500-Watt Reference-Class Studio Power Amplifier

This ultra-linear power amplifier is the top choice for recording studios
and post-production work, yet its amazing price is just the beginning. You
get true audiophile-grade performance that delivers 2 x 230 Watts into 4
Ohms or 500 Watts into 8 Ohms bridged, with enough overhead to always keep
you on the safe side. The A500's advanced convection-type cooling system
guarantees stable, noise-free operation, while its servo-controlled design
can drive virtually all passive speakers. A precise level meter and clip
indicators are provided for accurate performance monitoring. Input
connections are laid out on balanced XLR, 1/4'' TRS and RCA connectors,
making sure you never run out of connectivity options. Plus, the speaker
outputs give you a choice between professional ''touch-proof'' binding posts
and 1/4'' TS connectors. To assure years of trouble-free operation, we only
use the ultra-reliable Toshiba® or Fairchild® high-power transistors that
are known for their rock-solid reputation. In addition to all these
features, an independent thermal overload protection system with LED
indicators for each channel automatically protects both your amplifier and
your speakers. Last but not least, we have relied on a tough high-current
toroidal transformer for absolute reliability and lowest noise interference
possible.

You and your clients deserve the very best in studio power amplification.
Get the A500 and it will be love at first sight: it is super affordable,
super effective and super flexible!
