Default My rig

I have to admit I'm no EE, but I love to build and listen to audio components.

BTW Thank you, once again, to Pete Millett.

s.e. amplifier with vt-127A
Fellini's Amarcord. Can't post the pic I wanted to (due to forum rules -no titties) so this one should do.

How it looks the impedance?
Thanks for the schematic mindutis. Do i need any feedback in pentode connection?
@felixx: Right now i'm using some old tesla speakers with small diy horns. Just testing diffrent constructions. I will eventually build a fullrange system. I need something efficient and small. And not to expensive..

Smile Mullard 3-3 Stereo.. does that make it a 5-3+3 ??

I recently completed this little amp using the mullard 3-3 design, all the valves and transformers are ex equipment but most of the small components are new. I am realy impressed with the sound and for a low powered amp it goes quite loud. This was my first attempt at building a valve amp and next time I would like to build a SE design with a little more power !

Yesterday I finished Red Light District amp based on Russian pentodes 6p14. Polish custom OPT by 4pietro. Chassis - recycled from 3Com ethernet hub - did not have to drill LED holes.

Now sitting and sipping Quinta da Espiga, listening to divine Mariza. No v-liquid, SY!
