Hello guys


i sent this query to the info@dadaelectronics email but received no reply so i thought i would try here instead

hello stefaan


i am fitting your 405 upgrade kit for a friend. i have read fully the instructions and just have one question -

  •   To reduce the switch off noise of the amplifier we decouple D2 with a 2K7 resistor. The

    decouple resistor is placed at the copper side.

  •   Decouple the Zener-diode D1 on the copper side of the board with a 100nF capacitor.

What is the exact placement of the components? Do you mean 'connect these components in parallel' with D2 and D1 or something else?

thanks
neil

Hi, 

the upgrade manual says "To reduce the switch off noise of the amplifier we decouple (after we replaced D1 and D2 
with the new zeners!) D2 with a 2K7 resistor. The decouple resistor is soldered parallel to D2 
at the copper side. We decouple D1 with 100nF (soldered parallel to D1), also on the copper 
side of the Pcb."

Seems only one way to read this.
