The JE Labs/ Angela SE 2A3 amplifier, revisited

That's still by hand!

Agreed - my attempts with a drill press always look like someone with one eye and coffee jitters took a stab at things.

@Redboy , Would you mind sharing what that aluminum extrusion that crosses the mid-line of the chassis is and where you sourced it? It is that piece that the turret strip mounts to. TIA

Perhaps this link might be of use for the extrusion... look under the Channel heading in the Servocity website

Lay out with a sharp pencil and a straight edge/ruler with a cross where the holes go.
Use a spring-loaded center punch for your first mark.
Use a small, sharp center punch and a small hammer to make the mark larger. If the mark isn’t aligned perfectly with the lines, use the punch and hammer to push the mark to perfect alignment.
For the pilot hole, I like to use a new 1/8” bit (an old bit can ”walk” the hole out of alignment because one side will cut more than the other).
With the drill press off, bring the bit down to touch the mark. If the bit moves, adjust the work piece until it touches with no movement. Clamp the work piece to the table. Turn the press on a high speed and ease the bit through your top plate for a perfect pilot hole. Then step drill to the diameter you need.

Lay it out well and get a shop to laser/CNC it. Outsource.

Thanks. That mini channel is pretty close to what I wanted. I ordered a few pieces a while back and am happy with what showed up.

Would like to know where the angle, rather than channel, types can be purchased. Thoughts anyone?

Yup. Front Panel Express.

Test fit...

I'm still quite a few hours away from being finished, but look! The tubes fit!

The inescapable conclusion being -- you used the right kind(s) of sockets.



Let me know if you need any other affirmation.


(in all seriousness -- this/these is/are beautiful)

Love seeing your craft Nate!

 

[Thermionics]

Nicely done, Nate!

I'll be happy to break 'em in for you...you know, as a favor to you.

 

[gable]

Those do look very nice Nate!

Now clean your fingerprints off them

 

[djnagle]

Looking good Nate. Being aluminum you can anadize them gold.

 

[djnagle]

Or red, blue, purple.......

 

[MrEd]

Lookin good Nate.
You have a good eye for detail and tidyness.

 

[Wntrmute2]

Good ear too from what I gather.

that's a big 10-4.

Hey Nate, looking at your work I am reminded of the hours I spent with my erector set as a child. Looks like we're both still at it.

 

[marantzfan]

So, there was a guy busting my chops not long ago about not getting moving on an amp build...

Where are you at with this one Nate? It looked like you were ready to wire up and solder last I saw.

 

[Redboy]

Glad you asked, Anthony! I’ve actually been working on it lately, hoping to wrap it up soon. Pics and an update soon!
