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
