Little help with VU meters.

Hi, I was preparing to make this VU meter driver A simple passive logarithmic VU-meter on breadboard when I saw topic on this forum about this board:

This is schematic I planned to use for breadboard project:

By parts they seem pretty close, could I somehow omit opamp and power stage from this board and use it like VU driver from schematic? 😀

Will post sch from ebay board if I manage to find it, thanks.

I think IC is lm358n
