Hi Mr. Gabor
Me too, very much. As I was informed you presented this topology to the world, so I would like to express my great admiration to your work and would like to share it further among DIY-ers because it deserves it. Hopefully more and more people will taste this simple amp topology and realize how good it can sound. QUOTE]
Hello
I think these topology existed before I was born1 I'm only 4# years old. So I can't take credit for someone else work.
Probably I brought here to the forum?? Can't be sure.
I work on these topology over the last 20 years or so.
Yes it is sound great, simple, easy to improve it by choosing the right components.
So please keep going with these topology, keep up the good work it will give you a lot of pleasure and fun!
Greetings Gabor
A signal connection through an heatsink is not god at all. The elox surface is high ohmic.
Hi sonnya, i don't understand what you mean.There's no signal that flowthrough heatsink. Can you describ the location please?
Marc
cool looking little amp 
maybe time to go build that active speaker 
Marc, my compliments, very nice PCB-s you've made for VSSA. Your skils become topmost at designing layouts. Congratulations.
Thanks LC, but i am not totaly satisfy with result since board are 107mm with. Goal is to reach 100mm to fit in standard boards so that with a standard 100x160mm board we could eatch 2 amp board. In this way could i go for 2x1mf 50V instead ?
Marc
Marc, it can be done on 50 x 80 mm PCB, so 4 PCB-s out from standard 100 x 160 mm board. I'm working on that right now.
Yes but in double side with smt...don't forget i am for diy : etching bay me.....

Is there enough room between the output TO-3's for the 2 mica insulators (without the micas overlapping)???
