[TenTec] ARGONAUT 515 CONTROL BOARD

[Ed Worst]

I'm looking to the list for some historical information.

I have an Argonaut 515, Serial Number 0022.  When I was looking at the
Control Board, I noticed it didn't match the schematic in the manual.  The
Control Board in my 515 is identical to the Control Board in my 509.  Did
the low - number 515's start out with the Control Board from the 509, and
change later?  Or did someone put an old Control Board in a new radio?

Tnx es 73,
