Clap on v1.02 board [SOLVED]

I finished my first Nava v1.02. With exception of the clap all instruments work fine. Anyone here with a v1.02 board who has a working clap? Vincent, how about you?

I triple checked all components and also swapped all IC's and transistors. Also checked all traces. No success. The clap is missing the accent. I only get the reverb part. When opening the trimmer noise increases, but no accent.

Could there be an issue with the new boards?

same thing here. I can only assume it's the chip, because I get the same sound after removing it. :P

My clap seems to be really low in volume compared to everything else... The reverb portion is way louder than the crackling envlope, so it ends up sounding far more 808ish than the 909 should be. I wonder what's happening here..

This is the clap turned way up. Almost sounds distorted.... bunk BA6110 too?

Mind you, this is after messing with the trimmer, it's as good as it can sound... anything more and it's an even more distorted mess, but the crackle needs to be louder than the reverb!

I also had an issue with two faulty AN6912s. One in each kit, both with the same date code. Replaced them with ones from personal stock and it then works fine.

Any chance you have that date code?
