<< Hi.  I just bought my first R-390A.  The front panel tag says that it is a 
Collins Serial #1913, order # 8719-P-55.  The unit is complete with original 
meters and is in excellent overall condition.  Upon disassembly, all the 
modules in this unit are Teledyne from the 1963 contract.  The meters have a 
65-3 printed on the back of them and a lot of the pots have a 64 or 65 
stamping on the back.  There are also 2 B+ fuses, factory installed, in the 
back panel.  Could this all point to a 1965 teledyne unit that had a 1955 
Collins tag put on it??.

The Collins tag certainly appears to be an originial tag.  Is there any other 
indicators to help me establish if this is Collins or Teledyne.  It would 
seem strange to me to have all 6 of the modules replaced with Teledyne units 
of the same order number.  

Any help would be appreciated.


Thank You,

Scott

Welcome Scott...........What you have is commonly referred to as a "Dept 
Dog"..or "Dawg" if you are in the deep south.

When the R-390A's and others went to the depot for repair, the front panel 
nomenclature tag was removed. The modules were removed repaired and when they 
were re-assembled, whatever was grabbed first is what went into that 
particular receiver.

To see who built them and when go here..........

This is a common occurence.
