The Crown Jewels Amp

this is my Best Project
a Timbrical Imprinting Free amplifier
using an active load with the same output NPN device
that normally you find with Hexfet

You've outdone yourself this time Stee, this looks like something that actually might not blow up right after powering it up for the first time !

Do tell, how does it sound ? That Q6 follower riding on 100R resistor must be quite "Timbrical Imprinting Free", correct ?

Wow, Stee, you got somehow approved by one of the Big Ones!
Keep posting, Stee, your projetcs may not always been perfect, but a DIY forum is done of this as well!

Speaking of egos, eh ... Why join a public forum and boast about "best project" then ?

[Stee]

probably don't need current source for biasing, just a resistor
(to found a correct value for 1A bias see schematic)

it's also possible apply the same concept at driver's resistor (another NPN active load)

for better timbrical deletion
