very nice wood chassis.

 

are the white circuit boards the latest in trendy?

I hired a local friend to make the wooden chassis for me. He sure does a lot better job than I can.

I like it white, sir.

Looks great, Wachara!

And you can say the white boards keep cooler than the coloured ones.

Really a lovely amp, well done!

Really nice build, Wachara!

Those white PCBs are.... uh.... er.... interesting.

Did you make ventilation holes on top and bottom panels?

Love the wood, and great build.

Nice build Wachara!

It is a wonderful sounding amp. Nice oaky body.

For 350V it's not SUPER important. It gets hot but nothing crazy, some feet and some clearance from each face served me well for up to 8-10 hours at a time.

Eventually, I built this.  My first electrostatic amp.  

 

I used to have a SRM727.  It was a bad match to my DAC.  I then lived with a 10 years old  SRM-313 for a year.  Now I have this.  it really make a difference.  

 

Thanks KG, Headincloud and Enrique.  You guys have been very helpful 

 

Looks nice. Congrats.

I think that takes the cake for longest build

I want something small so I cut it into two half and stack it up.

 

It was made of soft wood.  It was only the materials available in the 100 yen shop downstairs (A shop sells anything for 100 yen).  The 5 pieces of wood costed me 7 dollars.

 

it was supposed to be a temporary solution but I think it looks quite OK.  

 

I am going to add a transparent plastic cover then use it for the time being.  BUT is it SAFE???

 

i hope you don't have any cats.

7 dollars? You were robbed! (only joking) But at least you've built it, so you have my admiration for that.!!

 

I've got all my parts now but I'm still sorting my chassis. Elm frame, brass legs and copper top. I like a bit of weight! I HAVE to build the chassis before I get the soldering iron out. I've just too many projects with unfinished chassis.

 

@nopants, I think this could well take over the title for the longest build, so don't pester me people.

 

$7 dollars was only for the wood.  The stainless steel screws cost a lot more.

 

 I wish I could do something like yours.  

 

 I planned to have somebody to make one similar to yours but I was just too lazy to do the drawing.

 

It took me a week to complete the drawing for my last headphone amp.  The builder asked for drawing in CAD format?  I had to look it up from wikipedia before I knew what he was saying   . (of course the builder ended up working from my pencil drawing)

I think you might have the right idea. Just get it built and enjoy it. I'll be lucky to get the chassis finished this month. Then the fun starts with the boards.

nice work and expect for more pictures.

Cheers. I'll post more pictures in a week or two when the chassis is finished.

My KGST is running too hot.  I can't put my hand on the top plate for more than 3 seconds.  I did drill some holes on the bottom plate and many holes on the top.  Should I put a lot more holes on the top plate?  Or would it be better to do more holes on the bottom?

 

 

 

By the way, it sounds amazing when it's really hot.

Just drop the current a bit in the CCS.  There are 300R resistors right next to the main heatsinks, change those to say 400R or something like that. 

 

Btw.  There is a reason why my amps have a completely open top and holes in the bottom.

FTFY.

Run them all at once and you don't need central heating!

You would be surprised by how warm our houses are.  Every house you walk into is at 20+°C so being Iceland doesn't really matter.  Well that and my amps aren't built for use in Iceland... 

@spritzer: the KGSS you sold me does actually get quite hot ... and does sound lovely
