Bottlehead Mainline headphone amplifier build.

Valorous crepuscule - anthropomorphs.

Many members may be oblivious to the open secret that when I am not moderating this sylphlike forum I while away the hours curating a Brobdingnagian Barney & Friends merchandise collection. Accordingly, when I latterly procured a Bottlehead Mainline headphone amplifier kit from EduanB I resolved that as l'hommage to the august theropod I will embellish the kit in a Barney & Friends themed colorway.

For those unfamiliar with the Bottlehead Mainline amplifier you may read about it here: https://bottlehead.com/product/mainline-headphone-amplifier-kit/.

The top plate and transformer bell cover as received from Bottlehead.


Here they can be seen with the first colour applied.


Here the top plate is pictured alongside my Barney & Friends bedding so that the reader may get an impression of what the final result is to be when the other parts are painted too.


Left to right: Protoceratops andrewsi, Tyrannosaurus rex, Ceratops horridus.

Stop that! Its silly.
I'm not having things getting silly.  Now, nobody likes a good laugh more than I do, except perhaps my wife. And some of her friends. Oh yes, and Captain Johnson. Come to think of it, most people like a good laugh more than I do, but that's beside the point.  Posting photos of your bell end; the very idea.

Not the Mamma!

Looking good Michon!

I remember an old newsgroup called alt.barney.dinosaur.die.die.die popular among the Barney haters. I was one of them because my daughter wanted to watch bloody Barney all the time....

Haha You should have shown her this video: Thanksgiving '97. The day Barney was killed - https://www.youtube.com/watch?v=epgXuMB1sF8. To this day I find it hard to watch.

I received an email early this morning from Dr. Thomas R. Holtz, of the University of Maryland’s Department of Geology, informing me that unfortunately the creators of Barney got it wrong. Tyrannosauridae were more likely a shade of gray. Shocking. Besides having to buy new bedding I also had to repaint the metal parts of the chassis.




The paint is still wet here.

This is the primer that I used.

I've also always been fascinated by that time in history when Diana-Dors ruled the earth.

Ga! It's the last time I comment on your colours  :facepalm: If you have a look at my avatar you can see that not everything is black and white... there is a grey area.

The new dyno colours will definitely be more appealing to dinosaurs wanting to buy the crack if you decide to sell.  :P

But for the record, jokes aside, I too like the new colours. Can't wait to see the rest.

Maybe I'll paint my next project in solid red as a dedication to our admin team's color.


Perhaps the HD800SDR headphones that I will use with the Mainline can be refinished.



The PVA has dried. Test fit of the top plate.


There is residual polishing compound on the left edge of the top plate that I need to remove carefully.


First coat of stain and polywax sealer applied to the wood base.




They spelt "Steyn" incorrectly.

That is really looking good!!! I was so concerned you were going to cover that lovely woodwork in some sickly fluorescent pink, purple or green goo  :puke:

Nicely done, don't pay attention to Curlycat, you know cats have eyes that glow green at night...   :giggle:
