Help to identify/date this TS-808

Hello folks,

I have an old TS-808 that will be leaving the fold soon, but I don't know that much about it. The markings on the board mean very little to me, and the sticker on the back plate (that would have had the serial number...!) is long gone. Here are some pictures:

Please help to identify what this is, when made, etc. Is there some sort of serial number or something that would still be there even though the backplate sticker is gone?

Any help is appreciated, many thanks.

Can't the chip be dated? What are all the numbers on the chip?

Looks like a 1981.

I guess the lack of an (R) kinda puts it in the '81 realm don't you think? I don't know how to date it with the code but someone here does for sure.

The chip is a 1981 chip (1223 the 1=1981), the blue electro caps will have date codes too but I can't see them in the picture.

I'd think that's 1984. That doesn't mean the pedal is exactly that year, but if the op-amp hasn't been replaced, it can't be any older than that.

I think they only made that pedal from 79 to 81
then they started the GE-9, that looks like a TS-9, instead of a TS-808

Wow.......lots of cool info here. So since mine has an "R" in the Logo:




That means it was around the first batch in the 70's?

Old topic but I want to ask anyway.
I got a vintage 808 with JRC4558D (0197 code on it) chip, blue electro caps (8024 codes on them), (R) logo and a power jack nut. However it has a serial number around 178xxxs. The serial and the specs does not fit with each other as it is written above. Can it be a rarity or the serial numbers are just not good for dating?

Any comment would be highly appreciated.
