I have spent the past few months trying to understand simple Power supplys abd building a few of them
I have used quite a few different designs..
- Gyraf 18-0-18 calrec psu
- group diy psu number 2
- bo hansens 48v phantom psu
I always put a blue LED with a series resistor just before my outlet terminals
One thing I have noticed is that when I power off the blue led takes some seconds to dim (sometimes 5-7 seconds)
Simple newbie question...
Is this the capacitors discharging?
And a stupid question...
If it is a viable way of discharging capacitors - is it sensible to place and LED with a big big resistor it into a High Voltage Valave Power Supply..
The idea being when the LED doesn't shine it's safe to play as all the capacitors have been discharged...
