This is a bit off-topic here...

I'm from Romania too, a few hundred km's north of you

I had sent you an email inquiring about the latest version of your evolution of Mr. Bittner's Symasym (schematic, maybe pcb, and in an ideal case, some extra documentation/measurements).

Thanks in advance
Cristi

I've send you an e-mail with all the necessary details for implementing "symasym roender style"
Regarding symasym, whatever variant may be, it will measure much better than folded cascoded amp presented here but it will sound a little bit "worse"
Keep in mind, however, that this is a subjective opinion.
I suggest you to test each variants and choose what you like more

Default class a/b folded cascode amp construction

Roender,

Can I have construction details for your amp?

I'll need pcb layout and building instructions for your amp.

How does it sound if I was to listen vocal based songs?

Many thanks.

Atiq

I can't recommend you to build this one because I don't have a finished PCB. Also, there is a small problem with front stages PSU.
I'll update the thread when all this problems are solved.

Default class a/b folded cascode amp update

Roender,

Thanks for your reply. I thought you already tested and finished that amp! What happened to the PSU in front end? I suspect it's minor. How do you compare this version with Mike's Symasym?

Cheers!

Atiq
