I have two input transformers that Im trying to figure out, they were custom wound for a console and no data is available, came out of either a quad eight or electrodyne console, looks like reichenbach, cinemag has no data for this one. Can anyone help me interpret my findings:
there is a black lead which definitely was connected to the chasis ground.
I believe the primary to be
yellow
orange
brown
red
and the secondary
green
blue
grey
purple
between yellow/orange I measure 6.9 ohms
between brown/red I measure 6.9 ohms
with orange & brown connected, I measure 13.6 ohms betweeen yellow/red
on the secondary I measure .725K bewteen both green/blue as well as grey/purple.
If I connect blue & grey I cant get a reading between green & purple.
Im assuming that the input is selectable between 2 diffferent impedances. Im pretty sure this was a mic input transformer (although not positive) so perhaps it could be strapped 150/600? does that seem right based upon my readings?
Where I am confused is with the secondary, I cant combine them to add so perhaps this was wound to provide two outputs?
My understanding of ohming out a transformer is primitive at best, any help on interpreting this data (or suggestions for any other tests I should conduct to determine what I have) is greatly appreciated.
CJ, where you at?
