lá bonito é o amplificador ,mas soa bem?
é para vender?
é pena essa Bulgarian Audiophile Society não ter uma versão em inglês..

I dont speak portuguese, sorry, but
I understand (when I read) almost all in portuguese...
Yes, amplifier is for sale.

Yes, it's sounds very well.
Later I'll post the schematic and tips for this project.

And the price is ........................................... (drums here)

The sale is not exactly the reason for my post.
Simply I want to show my last project.
And I want to share here my experience with tube amps.
Few months ago I posted in DIY Audio announcement for this amp.
The price is still the same (without drums ) - *EDITADO*
But I'm not sure I want to sell it...
Now I'm working on other project - 20W SE with more powerful russian triode - GM-70.
Finaly I have few projects of Back Loaded Horns with Full Range drivers.
I'll try to finish plans of them (I forgot my flash memory in BG)
as soon as possible and post them here.
