MOTM

I recently purchase a 44sp dotcom cabinet that included their 1.5 amp 
p/s. (+/-15 & +5).

Of course it uses the smaller 6 pin connectors with a single group 
connection.
I'm considering just replacing most of  the 6 pin .1 MTA  with MTA-156 .

Any ideas/warnings/suggestions on how I should handle the lack of a 
dual ground ?
The other option is to just connect my power distribution boards to the 
power one supply and use the MOTM cables that I have already.

best,


John
