Wiring shown overleaf will disconnect the battery when you

remove the jack plug from the input, and also when a DC plug

is inserted.
Snap the little metal tag off the pot to mount it flush

in the box.
You MUST use some kind of heat sink on the legs

of the transistors when soldering. They aren’t

keen on heat. Any more than 3-4 seconds of iron

and they’re toast.
Recommended assembly order:

Resistors, Caps, Transistors, Wires, Pots
I’ve incorporated the Current Limiting Resistor for the LED into

the board for your pleasure.

NOTE: + leg of C4 goes here       - apologies, I didn’t mark it.
