It looked a bit different, but if it's TVS it makes sense

probably two zeners with cathodes connected

before you do anything, make sure Lazy Cat haven't made any changes
first one was brought alive just a few days ago

Might be an odd symbol for Zeners .
Series opposite connected in this case.
*If* you had posted the rest of the schematic, function would clear the doubt, so please do it now.

@Renioo

Have a look at Andrew C. Russells(Member Bonsai here on diyaudio.com) new amplifier:

Ovation sx-Amplifier

excellent execution and documentation. Very recommended.

He has A/B amps too.

I liked Hiraga's amp very much

if 10-15watt is all you need...then its really sweet, absolutely

now I think of it, I used mine to drive Apogee diy clones
funny, but it worked quite well, while other 'normal' speakers didn't

It's the one to which Lazy Cat refers in first post of VSSA
I'm ready to change mind because I can't get those mosfets and other without ordering from few shops at once.

Whatever, I ordered Fet's and stuff, only capacitors and resistors are left, but that's not a problem. If I get it right, all resistors not marked are 0.5W?

Took long time, but finally VSSA is at home and everything is clear... I need to think about arrangement.
