I am using BC547B transistors for Q1,Q2. So, as told by u I would connect the 62k resistor(R2).
Thanx for correcting about the pot which was by mistake taken as 2k.
U considered 1V while calc. for 62kΩ whereas 1.5V for the 1.1MΩ.Why?
As there would be some drop across R8, I think the voltage of battery for Q1 Q2 available is nearly 1V.
As the ckt. is modified, are the values of other components also changed?
The stereo Jack socket has 3pins- 1 long one & 2 short ones facing each other. So, as told "Please note the stereo output Jack socket (J1) connections: only the two inner connections are used, leaving open the external one. In this way the two earpieces are wired in series, allowing mono operation and optimum load impedance to Q4 (64 Ohm)." the 2 short ones are to be connected leaving the long one. Also any of the 2 short can be connected to any point(1.5V/C of Q4). Is it correct?
