Fairly standard ncore build.
- Schaffner IEC inlet filter
- one balanced XLR audio input
- single pair of output binding posts
- van den Hul SCS-12 wiring to binding posts (quite a fight to get that in!)
- everything tightly twisted and cable-tied
- split ferrite on power supply cables to amp
- bicolour indicator LED green/red on front panel - with green (on) fed from auxiliary psu output and red fed from 5v relay standby
- 5V standby input from 2.5mm socket on rear panel to SMPS standby (also powers red standby LED)

ebay cases and feet from china. Case bodging by yours truly. It doesn't show too well in the photo, but I've maximised the separation between the mains power input and the SMPS output: the mains is tied up tight to the top of the case and the SMPS output is tight to the base.

I've included a rough diagram of the LED and relay standby circuit. I increased the resistor on the red side of the LED so it has only a dim glow on standby - it would be 220R for full LED output, but I found that way too bright.
