Supply capacitor charge indicator

For those like me concerned in getting shocked , this is a great and pretty inexpensive idea I took from Merlin Blencowe’s site

It consists in a small led placed in series with the smoothing capacitors of the power supply.  A 1N4007 is also placed in parallel for the cap to work properly.
The Led will light up as the capacitor discharges when the amp is powered off.
You’d better not touch the guts of the amp when the red light’s shinning!!

I highly recommend the books Merlin sells, they’re worth every cent.
