Home › Forums › Help/Technical Questions › 1975 Frequency Analyzer PCB Version
I’ve recently acquired an old PCB pulled from a 70s Frequency Analyze with some parts missing, but no matter how hard I’ve hunted online, I can’t find an image or schematic of a similar pcb. Seems to be a battery powered version, rather than mains and is marked with a 1975 copyright, the pots are dates 75 and 76. All the versions I’ve seen only have two pots physically soldered onto the board or are the larger box versions and it’s neither of these. Can anybody help me ID it so that I can find a matching schematic and get it up and running again.
Thanks
Okay ignore the above, It would seem I’ve been sold a turkey, I just opened my old Octave Multiplexer and guess what that is what it is.
