Some years ago I build this amp.Very very good results.
Now I want to make some improvements and maybe you have a few opinions.
The op. initially was LF356 and I know that amp has really good results.
BF 422,423...BF 469,470 and SK1058,SJ162.
The BF types it used because the feedback capacitance is very small and contributed to a high slew/rate responce.
My concern is to improve the op. and the active parts.
For op. I'm thinking on AD 829 or something similar.For replace SK/SJ I hear good reports about Exicon laterals or BUZ900/905.
A few ideeas will be welcome.
