To bring the ripple down in class A amplifiers on the no feedback design a better regulated supply is needed since using an unregulated supply where one relies solely on capacitors can get crazy untenable for the 100,000uf needed for class A amplifiers, so seems regulated supplies create a balance and we can use reasonable cap sizes. Class AB is so much more flexible
The regulator is part of the amplifier so deleted C11. With feedback in use only in the regulator increase the miller capacitor C12 in regulator to 1nf to stop high frequency oscillations. Updated is the schematic, frequency response and 20kHz square wave response
Apparently, an ex Blackburn, Mullard employee once said, ''.......if your Valve Amp sounds ''Warm'', it broken.........''
I love it.
Valve Amps don't sound 'warm'. They can (and should) sound as detailed (I always think 'warm' means dull (?)) as any other sort of Amplifier.
Just make a Valve Amplifier !!! 7 components and you're away !!!!

As they said audio engineers are like children with clay or building blocks, they will try anything they can😉
For guitar its not supposed to sound neutral. A solid state poweramp behaving and misbehaving like a tubeamp would be awesome. Many have tried. I heard a roland micro stack 408? That had very tubelike preamp sektion with great distortion. My feeling is however, that powersektion benefits more from being tubes(like) clipping is a good thing in guitar, organ and other amplification
