This Connector for an Amp Umbilical?

I'm, once again, beginning work on my El Cheapo (Eli's PP 6V6 integrated amp). I need to put the PS in a separate enclosure. I've got an old 9 pin (the correct # by my estimation) Amphenol connector (salvaged from some sort of video equipment) that I'd like to use for the umbilical if it is possible. The little gold plated pins are spaced ~.125" apart. All nine are in a pattern ~.375"x.375". Are those pins too close together for these voltages? Is the connector safe with a 360V B+ rail? If this connector won't work, I'll likely use one of these: http://www.action-electronics.com/ampcpc.htm For all I know though, my little Amphenol is equally robust.

It's the dielectric and the pin spacing which matter. AMP and Amphenol are two different companies. Both have a dizzying array of connectors.

FWIW, in amateur radio we used male and female octal connectors for outboard power supplies -- just make sure that the nasty ends aren't exposed to any finger parts.

I will probably go to purgatory for this -- but I have used 5 pin XLR's for tube stuff.
 
I used "amp" as an abbreviation for "amplifier." The connector is an amphenol. I haven't been able to find anything similar to it, and thus, no relevant datasheet. Here's a pic of the little guy:

I haven't used these for tube stuff but I like the AMP Series 1 CPC connector. They're rated to 600VAC and 600VDC. You can get them with any number of contacts from 4 to 37 and they will accept 14 - 26 gauge wire. A representative AMP part number is 206061-1.

I've used those little blue things you show for signal and low voltage/low current applications -- don't know if they're good for higher voltages.
