An intriguing 300B SE-direct-coupled-amplifier

[Antonio Tucci]

We have finally finished our HiFi system.
It consists of a 300B SE direct-coupled (two stage) amplifier + a couple of dipole speakers (with integrated ripole subwoofer).

It is simply fantastic ... as well as the authors of it (16 children of 10-13 years old).

Quite the contrary. Most of these children will remember this experience for ever. One or two of them may become part of the future generation of tube heads. DIY forever!

Not at all,we want to see more! 😉


Stunning!!

Get those kids to join the forum,maybe they could teach us some things! 😉

Keep up the good work!
I see tubehead prodigies in the making!

That's great idea to have the kids involved. I believe they would enjoy the beautiful sound from the amp and speakers they built.

Congratulations!!

Thats the coolest thing I ever saw, and the amps ok too.
