Modifications



The original does not use a 2k trim pot

VR1

. If you do not want to use the bias trim pot then

you can solder a 1k resistor holes marked with A and B, and also use a 1k between C and D.



You can use different transistors. For example, MPSA18 for

, 2N3904 for

and

2N5089 for

. You can also use 2N5088 or similar (matched) for

Q1-Q5



It is reported that tantalum capacitors give a better sound than electrolytic capacitors.



might work more intuitive using a A50k (logarithmic)
