Could you please help me by sharing the part list for R2000. Which Pins on voltage regulator I need to decouple?
Thank you

Hello
the 45H bulletin is for R1000 only and do not concern R2000.
The amplifier is using Power pack IC's in R1000 only and they need to be " decoupled "
Not a very complicate mod !
The R2000 is using discrete semi-conductors and need another mod kit with more components than R1000 : 16 fuse resistors , 5 transistors and 3 electrolytic capacitors
Again , nothing very complicate
I will strongly recommend to not use ordinary resistors instead original fuse resistors
