Does anybody know the actual current drain of an RNC off the top of
their head ? I have the 9vac version, and I know it *says* 500mA on the
back.

I am putting together a single power supply for all 3 and don't want to
unnecessarily overdo the current . But I am not where they actually are
at the moment so am unable to test for myself.

cheers

You can't overdo the current. Get a 1.5A transformer. Or if you really
want to cut the corners as tight as you can, e-mail
and ask the man who designed it.

1.5A 9VDC supply, $6.95!

A lot cheaper than a POS HP CD writer!

RTFMessage! This is a DC power supply (about a hundred of 'em - you
could have linked to the one you thought was the right one). A DC power
supply won't power a device that expects an AC input, at least not with
considerable modification.

Sorry, had no idea what he had, not like a RNC can't be the Republican National Convention!

Here you go, 18VAC CT....

Still not reading the message, then. The OP was asking for a 9 volt
alternating current supply, you have offered a 9 volt direct current one
and an 18 volt alternating current, albeit with a centre tap, so you are
throwing away half the cost. Still, with luck, you may get there in the
end....

I can't say offhand how the numbers work out, but I have two of them running
off a (10V at 1.2A) Triad FP10-1200 flatpack transformer, along with some
crossover electronics that probably take a hundred mA. The Triads are pretty
conservatively rated, they fit into a 1U case, but I think the 1.2A is the
largest one available.

If I was looking for 9 or 10 volts at 1.5A, I would look at the Amveco
(formerly Talema) toroids.

I used to buy standard 12V Xfmrs, and removed secondary turns to whatever I needed. Costly to buy non-standard voltages, 18V CT makes more sense.

You know, you scream at me, but it's Geoff failing to tell what RNC he has!

"rear panel view shows 600mA"...

Not sure why people continue with electronic stuff [rather than digital], guess they like turning knobs!! Like a pacifier.

Ring ring.
Hello, FMR Audio, may I help you?
I'd like to know average and max current draw for RNC blah, blah, blah...
Why certainly, it is blah, blah, blah.
Thank you, blah, *click*

Geez!

Heard back from Mark @ FMR.

350mA each with the disclaimers 'closer to' and 'in normal circumstances'.

So trying to power 3 off a 1A rated plug-pack daisy-chained would be
stretching things, so I'll go with the next-size-up transformer built
into a case option.

But it is Music, not a stable load.
