There was a reference to using a depletion mode JFET as a CCS to replace the BJT and it related components in the book.

But the distortion performance of doing this was supposed to be worse.

The only thing left to try is another BJT with greater hfe.

I used a 2N2907A with a hfe = 180 instead of the BC558.
