No, the OP said, IN THE FIRST POST, that it came out of A BOX OF PARTS FROM AN ELECTRONICS INSTRUMENT REPAIR SHOP!Was it from an older type radio, one with a tuner?
Short term memory loss I guess. Yes, I did read it. But I got more caught up in what it might be and in figuring a way to determine what it might be.Why do people only read the question in the titles and not the background info in Post 1?
I don't see any bumps that indicate capacitors. It may be just a custom resistor network. Might have a chip.View attachment 118717 It looks like a ceramic cap but it has 8 leads. Found in an old box of parts from an electronic instrument repair shop.
As noted by other contributors, the imaged device is what amounts to a 'very small scale' integrated circuit (actually, a small, 'potted' PCB) of, it appears, the 'Sprague 'Bulplate' line (or similar) -- I have, in the course of my avocational pursuit of 'vintage' electronic gear restoration, 'collected' considerable data on such items -- Please post the device number, etc.. (or, better yet, a 'close-up' of the device clearly showing such marks) - I may be able to provide you with a schematic and application description...View attachment 118717 It looks like a ceramic cap but it has 8 leads.

Thanks @GopherT !He already posted high res photo. Click on it to enlarge (post #1)

Good deal! -- For the benefit of anyone needing to 'reverse engineer' such an item, please be advised that the combination of a cheap (<$200) LCR indicator and a simple (i.e. single plane) radiograph of the device makes a scant 30 minute job of it!Thanks for the help everyone. Curiosity satisfied.
Good find!
...and where does one get a cheap radiograph (commonly called an X-Ray)?Good deal! -- For the benefit of anyone needing to 'reverse engineer' such an item, please be advised that the combination of a cheap (<$200) LCR indicator and a simple (i.e. single plane) radiograph of the device makes a scant 30 minute job of it!
