Does the enclosed help?

If you have a double pole switch you can use one pole for HT and the other for LT. Just be sure to get the connections correct!

If you follow the example, you put the HT switch just after the battery / power supply. Then the earphone socket is 'dead' when power is off. Then the switch shown on the original circuit (the cross) is not needed you wire the bottom connection of the pot to the 0v / earth line.
