Thanks Vunce, is that the voltage at the 604's legs? I'm guessing that you don't see any switch on/ off spikes, due to the Rs resistance and the local capMine are fed +/-23V5
You could increase the Rs resistors to drop a bit of voltage feeding opamp.
I'd also like to know why everyone is using large(ish) local psu caps on their boards. Thanks
This does beg the question; Is ESR the absolute concern for a power amp OPS local decoupling cap? Ie what is the point of placing huge capacity/ ave ESR caps on the board (Wurth 10,000uF, etc).
To my mind the larger metal cans will pick up more radiated noise from the transformer. Just trying to understand what people were thinking here.
