Umbilical cord construction

In the end, isnt it about total power. Heat is ultimately what destroys anything. If its rated for 50V and 10A, isn't this the same as 500V and1A. Speakon or Powercon are the cheapest and most effective option I have found.

i wasnt referring to this design, just the connectors in general will handle higher voltages than spec, but you have to watch the current. creepage is about voltage, pin size (which is the limiting factor here) is about current

Umbilical

Thanks for all the helpful response to my original questions. I believe I have found a good connector to use--it is on page 1503 of the Mouser catalog. Rated 600v/3-7.5amp, up to 7 pins at 20 gauge. Within budget.

Any comments would be most welcome.
Thanks again.

Umbilical

It's the Conxall Micro-Con-X series connectors. Page 1503 of the Mouser PDF catalog. I would attach it to this reply if I knew how--sorry.

Are you just mounting the power transformer remotely?.......or additional PS components?

If it's just the transformer, you'll need:

B+ CT 3 conductors
rectifier filament 2 conductors
6.3V CT to run filament regulator 3 conductors or 2 conductors (depends on output tube choice IIRC)
chassis ground 1 conductor

Will noise be an issue with all these lines running together? I have always kep mine separate.

If it's just the power transformer separate, then everything is AC (and ground). Once I separated signal and chassis ground on my umbilical, the noise problem went away. I'm running 95db fostex full rangers.

Good question if one is running rectified & smoothed B+ in the umbilical next to the AC filament conductors.....

I was running DC and AC together. That's why I used coaxials for DC. I think rg58 withstand 1200V.

you can actually get lemo, cannon, amphenol etc connectors that have mixed contacts, low level (or high level) shielded coax, slightly higher current pins and massive 10mm conductors if you like. but these things you start to have to make loans to pay for
