any experience with this ?
especially interested to know about connectors etc
photos would be nice too....anything goes
For preamps I have used Neutrik Speakon pro audio connectors with great success (the metal ones). Voltages up to 400VDC no problem so far, even though they are not rated for such use. The pins on the chassis and cable connectors are large, well spaced and easy to solder to, so I can use 15.5ga. litz wire for my returns with no problems. Nice satisfying "click" when they engage, as well.
Check out the pictures.
The specific parts are:
NEUTRIK NL8MPR-BAG SPEAKON 8 POLE CHASSIS MOUNT
NEUTRIK NLT8FX SPEAKON STX 8P FEMALE CABLE CONNECTOR NICKEL
Available at Parts Express.

Tinitus hi!
I used to build pre amplifiers getting their power from the main amp's supply. What we used back then was an octal tube plug and socket this gives eight pins and worked fine back then
Now to find themgreat posts, thanks
since its high curent, I might use a 3-pin IEC, also mentioned by redshift/Tyler
but its really a standard for mains voltage, so I have to make sure noone connects it to mains
solution
mains power chassis plug is always a male , and detachable mains cable have female connector
so, power supply could have female chassis plugs as DC output
and power amp mounted with fixed cable having a male connector
using ultra short cable, and angled connector, it could be ok

Why not use an Industrial Power connector?
There are tons of them, they are designed for exactly that purpose and NONE is even remotely close to a line power connector, which is the most dangerous design idea in the world.
Here you have a few.

No need to use incompatible XLR/Speakon/Line/etc. connectors which to boot have the high possibility of causing terrible mistakes.

thanks, I have never seen those
yes its as you say very dangerous and wrong to use AC line power connectors for DC
and the female chassis plug I suggested to use as DC output is designed for AC output chassis plug , yes
but personally I have never seen any
but Im not happy about it either, no
and one reason why I intended to mount a fixed cable on power amp, with male connector...its fits nowhere else
but still looking for the right one
No. Use something that is different than what your mains power is. It's the only safe solution.
IEC comes in a big variety, you don't need to use the same ones as your mains. I didn't.
My mains on the left. My DC cable on the right:
