Advice on connector type for outboard PS

Captn Dave · 18th September 2009, 04:08 PM

I'm planning a phono stage with an outboard PS. I will need a connectors for the B+ power cord. Other than Cinch-Jones and molex, are there better choices?

Personally, I think the military style Amphenol olive drab circular connectors to be the best, at a ridiculously high price.

Use coax cables, the type used for radio transmitter antenna. Theses are rated for high voltage and don't cost much. Also the B+ is completely encased in a protective braided sheild. You can buy these cables already made in any length or make you own. The crimp type need a special tool but the clamp type screw together.

Buy them here (and many other places)

There may be better choices, but I've used octal sockets, both 8 and 11 pin with matching male connectors with success and no problems. Just remember to ensure that the energized end is the female end, so if the power supply is "turned-on" while disconnected, no dangerous live pins will be exposed.

Triode Electronics Online sells them

3pole, 4pole and 5pole XLRs are available in a range of plug and socket types.
these can take adequate current and voltage for a PSU.

Just my $.02

#1. If the Phono stage has any significant value B+ capacitors on its chassis, the exposed pins of an octal would not be a good idea.

#2. Chris A's idea along with Andrew's look to be about the safest and relatively secure.

#3. One thing I would consider is avoiding any connector that is the same as something else you have at hand. ie; if you have XLR's in the system avoid them.

#4 Be sure to take into account kids pets etc. Personnally I would use something with 4 pins so that you can run the primary (120V) through it so that it "kills" the supply when disconnected.

...then plug them into microphone ins.

PS cables must be unique.
