Gentlemen,
here is another project I completed:
http://www.tubes.mynetcologne.de/roehren/6v6se/6v6se_e.html
It was intended as a birthday present for a friend to be used in a small room with small bookshelf speakers.
It is a small 4,5 Watt/channel pentode/pentode single ended integrated which gives a damn on all this "single ended triode without any negative feedback" madness.
Instead, it is a no-fuss, well-engineered, solid all-pentode circuit amp, which simply does what it is expected to do.
If you are interested in the circuit development process, you can find it described extensively in the form of a moderate level walkthrough, starting at:
http://www.tubes.mynetcologne.de/roehren/6v6se/schematics_e.html
May this walkthrough help other tube DIY amp enthusiasts construct and enjoy their own "no fuss" amps and bring back a wee bit of solid engineering in this world of audiophool madness.
I would like to thank the crowd at "The G33k Zone" http://geek.scorpiorising.ca/GeeK_ZonE/index.php who helped a lot in making the schematics section walkthrough come true.
I wish you and your relatives a great new year!
Tom

Are the OT avabile on the Net or are them from a local manufacturer? They seem interesting, with all those primary connections... And I assume they're pretty cheap.
Hi Giaime,
They are from Gerd Reinhöfer, a German winder. His site can be found here:
www.roehrentechnik.de
The ones being used in this project are intended for "experimentation", therefore all the taps.
Although experimentation types, they perform well enough to have made it into this amp finally.

Always a pleasure to read well documented projects. And the documentation for this one was in category A+. 🙂
Well done, Tubes4e4!

It is indeed very well documented, but very simple to understand.
I propose this as an "ufficial" walkthrought 😉

Hi Tom, you have a great website, very informative with lots of useful information. I go there a lot.
Where do you get the mounting boards for the components please?
Thanks.
Phil.

Hi Phil,
Those solder tag strips are still available at local electronic components shops over here in Germany - they still are in production.
Also, they are available at any well sorted E-parts mail order company here in Germany, called "Lötleisten" over here.
There are many web shops for DIY guitar amp gear that stock them, too.
I like them - they allow a components placing and wiring technique somewhere in the middle between the extremes of PCBs and pure point-to-point wiring.

They are manufactured by both Cinch and Keystone. Any retail outlet with those as one of their suppliers can get them 🙂
Wow, here's GeeK. This is starting to be a GeeKzonE island here in diyaudio!😉
But I miss tubey smileys
Webmasters, do something about it! They are GREAT!

An externally hosted image should be here but it was not working when we last tested it.
