Nice work bud!!

I don't recommend any use of the drywall anchors in your PL400 project Eric

Agreed, meticulous work.

Always at the ready for when the wife decides to rearrange the house on a weekly basis.

Cleaned up the mid-plate, removed the old LED boards and mounted the new.

Wiring to one of the pots was horrific.

 

[Hexis22]

Also finished up bakplane boards and stated housing assembly.

I can feel the magic already !!!!
Very Nice Work!

Made some progress today:
- Installed transformer with isolated bolts (did not realize S2 transformer was 1/2" longer than S1)
- Assembled rectifier with caps
- Placed sheathing over AC primary wires and positioned tiedown supports on backplane PCB - much easier to route solid core S1 transformer wires... They stay in place.
- Finished up main wiring and performed initial power supply test

It''s alive!! +/-85.2V with 120V AC input.

Of course you have two flukes! Beautiful..

Eric, excellent! If you ever wanted to build amps for clients, you'd probably stay very busy.

Two is one and one is none... At least that's what I tell the wife when talking about tools.

The Fluke on the right is almost 30 years old and the LCD is starting to fail unfortunately.

Thank you very much.

I really enjoy working on this type of project. It's a great combination of making it work electrically and hands on mechanical assembly. It's been a welcome distraction from the Midwest winter.

I would welcome building amps for others...

After correcting a stupid wiring mistake to the DCP board (J3 pins 2 & 3 were swapped) all remaining connections completed, verified, and voltages confirmed correct.

Just need outputs installed and meters connected.

I've got an 87 (with no version number like this one). It's never been in for cal but still reads consistent with calibrated instruments.

Decisions, decisions...

Do I go Black, or stay with natural finish.

I'm leaning towards Black to match my Aragon pre, but need to find Black anodized handles. Anyone have a good source for quality Black handles?

All things Handle related should start here. I have used their products for years. Fast shipping, very configurable. Painted/Powder Coated/anodized

That's perfect!

I saw reference to that site in the past, but could not find it.

The inside of your amp is super sexy, I'm thinking you can have it any color as long as it's black!
Very sexy to match your Aragon Pre......
Just sayin'
My 2 cents.....
