This uses k1058/j162, the circuit diagram looks like a goldmund clone.
But why does this kit have a vbe multiplier? Does it work?
I'm new to vbe multiplier on an amplifier using lateral MOSFET.
In general, sort of. The trail starts with the Hitachi application note circuit: differential input, differential driver, source follower output, then the Maplin exact clone, Maplin like clone and countless hifi and PA clones with various part substitutions, then the Goldmund circuit adding follower drivers and then individual follower drivers and finally the Chinese clones .... well doing their thing on cost saving clone designs (cheaper unmatched part substitutions etc.) that at times don't sound or behave anything like a Goldmund. Some sound really good, others not and some are dangerous. Caveat emptor.
