Long time listener, first time caller.

Hi,
I've long appreciated audio and have decided to delve into building my own tube amplifier kit. I got into audio because my mom worked for bang and olufsen in brussels back in the late 70s/ early 80s and I inherited all the equipment she used to sell. I think I killed the beomaster 1900 with too many dorm room parties in my 20s

Anyways, I picked up this 6n9p+EL34 13Wx2 HiFi Tube Amplifier Kit on ebay as a christmas present to myself.

My idea was to pair it with these Bose 6.2 I picked up off craigslist and make a nice little system for my desk. My audio source for now will be spotify on high-definition + a FiiO D3 DAC. Nothing too fancy :tresbon:

My background is european automotive and mechanical refrigeration.

I'll track the (hopeful) progress of my build on this thread:

update:
I found some documents online that I'm using to guide me through the build. I'll also try to post relevant pictures to help anyone else who is building the kit (please point out any errors you might see)
Schematic that I found online which matched the little the seller gave me:

My Progress:

Transformers & wood paneling on (not pictured: my bruised hand from the sharp edges - haha)
*tip make sure the metal frame is square before attaching the wood sides, mine now sits a bit askew :-/


Notice the orientation of the transformers by their wire color/count. Also the "H5" is mounted upside down below the transformer. The bulb sockets have the #1 terminal at the 7 o'clock position from this vantage point.

I also picked up some rubber grommets from Radio Shack to protect the wires as they protruded through the stainless casing:


Work Space turning into a bit of a mess:


I also picked up some electronics board from the shack to clean up the capacitor wiring (upper left hand area)


Detail of the Left (or right? lol no clue) channel:


Wiring Complete (atleast no parts are left - yay!)


With tubes installed:


Test Run (Excuse the song, it was stuck in my head during the build process)

That glow

C&C welcome

Currently paired up with spofity on max bitrate, a fiio dac and my macbook pro. Listening to some of my favorite Miles Davis, Dave Brubeck or even Emma Shaplin brings out color that I had never noticed. Quite enjoyable! Now I haven't had much listening time with the bose 6.2 nor tube amps at all, so my review only carries so much water. That said, no weird humms, distortion etc. All in all I'm a happy

Hi Julien. Welcome to AK. That's a nice looking kit. I'll enjoy watching your progress. Very cool your mom worked at B & O. Not too many of us can say that. Cheers.

You got that right....178 bucks for all that! It never ceases to amaze me at how cheap those Chinese can produce goods...and think the guy selling it is making some kind of profit.

Rank over....

hope you enjoy building it

I have been wanting to get a decent but cheap tube amp kit and that one with a few others have been in my sights. Would be interesting to see how the build goes and how it ends up sounding.

Welcom to the club

We are a few located in europe, i'm in sweden.

It is $ 300 with shipping , i would think some of the profit comes from a bit of the shipping .

It is still a good value , even if you were to buy better output transfomers for it
