TI power stage for selfoscillating amplifier

[Reactance]

LM5122 as a boot stage very costly ? why not use TL494 and boost with that. single rail,

Too much functionality for the 494.
First of all I use a synchronous rectifier, secondly FORCE PWM mode will be used for small loads, because otherwise the boost generates disturbances noticeable for a high quality amplifier.
Besides, in the multichannel version I am going to use a biphase interleaved boost converter, so I will use this board also for testing.

Odd technical remarks on the justification for part selection, I cannot seem to agree with them but its your baby let that be.
