• 

You can use either 20k or 25k for the trimmer if you cannot get a 22k.

• 

You can use either NOS MN3005 (if you have one) or the new Xvive reproduction MN3005. No, I do not know where 

you can buy genuine NOS MN3005…sorry!

• 

You can use other BJT like 2n3904 or 2n5088 for the MPSA18. Just mind the pinouts if subbing transistors.

• 

Using a silver mica or MLCC type cap for C30 (100pF) will produce optimal results (due to tighter tolerance).
