Hello.

I read some schematics of TS-808 and TS-9.
For CR1 and CR2, I found out several patterns.
51pf cap with 51k reg, 100pf cap with 47k reg and 1nf with 100k reg.

Which is correct one? I mean which one is the same value as vintage ts-808 and ts-9?

If you know, Please let me know.

Thanks.

Ibanez used 100k + 10nF, 100k + 1nF or 100k + 470pF in their flip-flops before turning to CR units...

Then, for what about your question, any of the above will work for a repair, which is the "vintage" :scratch:

BTW

If you're going to restore a vintage unit, you should find 2 CRs, whatever value, and make your restoring.
If you're going to clone a TS, then who cares what's the vintage value as long as it works?

I just want to make a prefect replica of TS-808.
