Hi all, I have bought the upgrade kit from here and the upgraded caps.

I have just been going through the guide and circuit schematics and I wanted to check a couple of things.

Do I need to upgrade the cabling, I am sure I read somewhere this was not needed as the 909 already had the upgrading cabling?

Second question is in regard to some of the instructions. The confusion is likely because I have a very limited understanding of electronics. 

Could someone please elaborate on what needs to be done with the additional decouple caps for the zener diodes D1, D2, D12 and C7? 

Very grateful for any help

The 909 cabling is best left alone as stock. The 8 decoupling caps are soldered on the solder side of the two main boards accross the appropriate diodes D1,D2,D12,C7as per the DA DA instructions.There is a good picture showing how to do this. Regards
