Hi all,
opened up my old Rogue Moog synthesizer. I'm trying to identify all the "old" parts in it, but some are easier to find than others. All the elco's in my Moog are Matshusita, now known as Panasonic, really good quality elco's; ESR is perfect, even after 30 years.
There are some TI IC's, two great tempco's (Tellab Q81's, not available anymore), but there's a brand of caps that I'm unable to find online. All the polyester/ceramic caps have "Mexico" printed on them, so I'm guessing that's where they were made, but I can't find the company. They all have a mysterious symbol, best described as a compass needle (or a double flag, or double arrow, or a diamond, or a double triangle, believe me, I googled all possibilities...).
By accident I found a picture online of the exact same ceramic cap (I googled for "S3N", which seems to be the dielectric material), but there's no brand mentioned. You'll find it here: http://www.vetco.net/catalog/images/VUPN6742.jpg. The ceramic in the Moog is a 100 pF, 1000V (which seems extremely high by the way, any ideas why?) Maybe "S3N" can be a clue, since not a lot of caps seem to use this dielectric material (whatever "S3N" maybe, can't really find much info online about that either...). I found a company called Vishay who make caps with S3N as dielectric material, but they don't seem to use that compass needle symbol.
The other cap in the Moog that also has Mexico and the strange symbol printed is a .01 uF 50V cap, with axial leads, that looks a bit like a small resistor or diode. No picture of that one (yet, I might upload one if extra clues are needed).
So all you vintage electronic freaks 'n lovers out there, care to join me on this treasure hunt?
