Ok.......here's what I have. Sorry I did not make it more clear earlier.
525 1096 4 diode mixer (diodes not marked)
525 1188 4 diode mixer MBD101 (I think) diodes
525D 1810 ND487C1 (Argosy II front panel)
525D 2591 ND487C1 (Argosy II front panel)
Hope that helps. Maybe Kent, N3KB will chime in with the S/N of his Argosy
II which has an Argosy front panel.
BTW I don't use all those Argosy's. Two of the 525D's belong to my two
daughters. I'm currently updating them with identical mods. :-) One of the
525's is my "beater" rig. It is all beat up, bent, dinged, scratched, you name
it. Really ugly. No, I didn't that to it. Bought it that way for about the
price of
a cup of coffee and donut. But it works just fine. That's my "throw it in
the
back of the truck" rig. :-)
