Hi grisk, welcome to the forum.
Not having a AD3600ip, I can't tell you if the power supply is similar or is indeed a completely different design.
Assuming there are some similarities, if you mean the RC network across the TRIAC (TR1 on the AD3000ip), the values are: R1 = 100R 2W and C6 = 104 (100n) 400V.
If you have to change the TRIAC, it's a BT137 (on mine, anyway).
