[R-390] Manufacturer of R390A

[scott]

Ah yes, a newbie.   I was one 8 weeks ago and asked the same first question.
Well this is what I have learned from these fine gentleman on this list:
There may be no one "correct manufacturer" of  this unit. It may have had
bad modules swapped at the service depot.  It is possible that you have 6
different manufacturers in this set and the name tag of a 7th on the
front!!!.  The modules should all have the manufacturer's name stamped on
them.  The chassis may or may not.
You need to check out your modules.
Don't fret though, it is pretty normal for these sets to be "mutts".  You
still have one of the finest performing sets ever made, mutt or not.
I was able to determine that my 390A was a pretty pure Teledyne unit because
all the modules were Teledyne and the front panel pots and meters had date
codes of 1965.
My tag was a 1955 Collins though.
You may be able to tell the same way.

Here is contract info on 390a's

number.
