Do you like Gain-One Amplifier?

[Stee]

this sounds great design

the divider has a total feedback
This allows you to isolate the gain of a single stage free

who is good at designing PCB?

upgrade

with a new bias (complementary Vbe multiplexer)
and double driver

 

[Stee]

second version

1R5 on final devices can generate 150mV
then Vbe bias should be 450mV 😎

Hello Stee. Interesting bias regulator. Are its bjts mounted on the output stage heat sink, and/or get bias stability via the 1.5 Ohm emitter resistors?.

 

[Stee]

yes - of course

power resistors can avoid to reduce base current
I'm thinking about MJE15031/32
8A Ic

Hello Stee. I am impressed by your ability to generate [or mass produce] schematics which teach and inspire. It is like when it rains it pours. Downloaded your zip file, and peaked in it. Will study it. Thanks, and best regards.

thanks a lot Antoinel
