The amplifier build went so well, and it sounds very good, so I ordered the Pre-Amp kit and built it over the weekend.

Some photos of the build.

The controller board. This is a two sided board. The push buttons and LED indicators are on the other side and protrude through the front panel.


Getting them to line up was not too big of a problem. I can see where it would be to someone who is a sloppy solderer. 


Testing the controller...




The input selector board. The gold plated contacts were optional.






Testing the input selector...


Base kit is complete.


The headphone jack is missing on purpose. I also ordered the optional headphone amp and phono stage.


A makeshift stand for everything. Made from 2'x4'x3/4" Veneered OSB shelves and some old speakers I had in laying around. Ah! Just like the college days!


After listening to the pre-amp for a couple of hours, decided to build the headphone amp last night. I was up until 3:00 am listening to it. It sounds amazing.

I only have one question: Did you go outside to look at the eclipse?



Great work on the electronics, mark. Thanks for sharing your projects with us!

I did go outside very briefly to catch a glance at the eclipse. I have seen many lunar eclipses. Pretty much seen one, you've seen them all.

Solar eclipses on the other hand... I will travel to see the next one. The last one, my first, was so sublime. I need to see it again.

Once I get started... 

Decided that since all my customers have the day off, I would take the time to build the phono pre-amp.

Progress shots...







I still have to do the wiring and mounting inside the main pre-amp.

It will be tested tonight!

Waiting for your evaluation!
