<DIV><BR>The ELPAC with +5 2A , +12 1.5A -12
.5A that we have should be ok to test it with then
as the 5V is a little higher amperage than yours that is operation.... a
little higher.. but yes if it runs warm a good idea to
replace!</DIV>

face=Arial>No, Ed, I got the MM-400 here mounted inside a RCA TR-70c quad
VTR. It is hooked up to the machine's supplies.</DIV>
<P></FONT>I removed it and used a workbench supply to measure the current
consumption with.</P>
<P>There is no name or data on the bench supply I am using here. It is a
common, general purpose, open frame switching supply.</P>
<P>One detail I noticed is this one is probably not big enough in the +5v
department, it got pretty hot after a few minutes, but didnt go up in
smoke.(yet)<BR>I think I would suggest trying to find one with
about a 5-6 Amp rating on the +5v output, and maybe a 1-2 Amp rating on the +-
12v supplies.</P>
<P>I had tried using a 3 amp linear for the +5v before, but without much
luck. I guess the inrush current is too much load and causes the regulator to
shutdown(protect).<BR></P>
<P>Hope this helps!</P>

<P>Ed,</P>

<P>Will this help?:</P>
<P> </P>
<P>I took the plug apart on the MM-400 here and measured the current(s) with
a Simpson 260 analog VOM</P>
<P> </P>
<P>+12v= 370ma</P>
<P>+5v = 1.81 Amps</P>
<P>-12v = 300ma</P>

<DIV>what are the currents on your oversupply I
went out and triaged some of the influx here that the
magni was in and found.... ELPAC with what seems to be the
same connector and +5 2A , +12 1.5A -12 .5A</DIV>
<DIV> </DIV>
<DIV>the elpac# is WRI3031 ( the WRI are all alphas the 3031
is all numeric. says... output 30W</DIV>
<DIV> </DIV>
<DIV>is this the one!? if so we know
what to look for on ebay to make other magnis work!</DIV>
