Here is three of my creations.

On the left the 6N1P Headphone Amp schematic by bruce bender.

Middle Phonostage and the right one the Power supply. Both schematics by TriodeDick.com.


Friend of mine has photography as hobby. And he made this awesome picture for me.

What iron did you use? Or rather, where did you get the covers. Love the look of the SS plate with the hex head cap screws.

You mean the transformer covers ? Or the grey plate ?
Both are actualy the same type of thin metal.

I welded those cover my self. And sprayed black mat paint.

And the grey plates are sand blasted with pearl sand. And later sprayed with "Plastik Spray ".

Here you can see both metal parts without paint/sandblased.

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

Nice job! Half of me was hoping they were custom, half of me was hoping they were off the shelf as I'll need covers for some caps and iron.

KT88 OddWatt Amplifier in his new home

I build the OddWatt amplifier as schematic is provided by Bruce Heran, but my first try didn't work out too good, because everything was in a too small enclosure. Now I have everything in a much bigger Hammond and no more noise. I put the PSU on a little PC board, keeps the amp nice and tidy. Here are some pics.


Kind regards from Holland

Sorry about no additional info.
My plan was to make a kit for beginners, that I can use too for workshops.
Main priority was easy to complete (octal instead of noval because of more space between pins), easy to get parts (6V6, output transformers and mains because equal to EL84) and good prepared chassis.
So I prepared a drawing of the board with EI84 size for transformers and three octals.
Backsite with spaces for connectors.
The Aluminiums were CNC made by a factory round the corner.
So some amps were finished and worked well.
Hoping now some more about that project.
