Inverted back plates build

[grapplesaw]

Finished control board wiring
Only front panel to repair and finish wiring it

I like the harness clips to hang off the wiring,,,,,good idea....

 

[grapplesaw]

So what has changed
my HDR photos look very bad when posted
is there a change to the image size in the forum?

I was doing something different with this build so I try several new ideas. I spaced the control board about 1/2" higher to give more room and cooling area
The clips made it easy to hold the wiring about half way between the back plate and control board

Mmmmmmmm
I will investigate

With the power running on the bottom now it's a direct shot to the Transformer

Glen, on some early builds of mine I actually relocated the AC mains in and fuse to the left side between the big caps. That was actually a pretty clean installation...

Ok here's the whole story. I saw your posts some years ago about doing just that. I believe the cord came out the side by the transformer. I did not want to have the power cord showing like that so never wanted to try it. After looking and thinking about it I drew up a wider chassis and discussed the potential to build it at Joe's fabricator. Joe said it would be way to expensive so I ditched the idea. Having purchased a chassis from Joe I was eyeing at the left over and thus we have this build. Go or bad it was just fun to do.

I agree Glen , I think yours is a good build. It's good to see different ways to do things...

Here's a test photo. Does this seem big?

 

[laatsch55]

Big is relative...

The hardest part was putting in the drivers. I remembered something about magnets so I got out my little pocket magnet pencil It made things much easier but still was a fight
I found that checking the leg alinement in an old base helped a lot
I must have stewed up something with the little inserts as they stuck up from the board. Did I put them in from the wrong side?

Here is the DC offset at outputs 3mv and .8 mv

Any fine tuning this ??

I will have to redo this one
I just noticed it was set on Ac volts

Well you got me after all Lee!!!

 

[grapplesaw]

Bias .35 v

 

[grapplesaw]

Rail voltage 207 vdc

I hope the rails are DC.....seriously Glen, good to see it finished....how does it sound??
