TSSA - The Simplest Symmetrical Amplifier

Thanks bwaslo :)

The basic circuit relies on high class A current. So to perform just decent it should operate at atleast 2A idle ... So rising the voltage to 40v means a lot of heat. Also the arrangement with collector into base of the output device with no basis to emitter Resistor to turn the power transistors fast off would mean slow turn of as soon as it leaves class A.

My tssa v2 to V8 is a lot more complex to keep it all running as you already had figured out. But Then it is possible to run it In class AB without sacrisfying Performance

If it's going to operate at 2A idle current the heatsink cannot hold that much heat generated , this is the reason why I avoided Class A :( but I'd like to try my hands on point to point wiring but not on a Class A :confused:

Thanks Sonnya
 
Fully symmetrical amplifier

Good day folks so I am currently looking for information on a fully symmetrical amplifier. Attached is the topology that i am focusing on. All I have is the topology that was given to me and i am getting difficulties in finding the book where it was taken from, could anyone assist me?

Thanking you in advance!

Hi
Symmetrical topology you are exploring is VFA which is not preferred in this thread. TSSA is CFA in CF output's configuration ie. voltage driven CCS. I would kindly ask if you can please proceed to find help in some other threads. Thanks for understanding.

May I suggest #7 - here - http://www.diyaudio.com/forums/solid-state/248105-slewmaster-cfa-vs-vfa-rumble.html

That's a page from the now defunct Audio magazine.
It's from an article the LOW TIM Amp project by Marshall Leach of Georgia Tech.
I think in memorial to him, the amp web site is still up hosted by the university.
