not the prettiest build, but i'm learning. goal was to make it work, and worry about the looks later. metal works was something new for me, you need to have good tools. these are my first two amps i have ever built. lower one is SS dynalo. edit: looks like i can upload maximum one picture(500 kb).

Milled a new “corrected” board on Sunday. When populated and ready for test the bloody thing worked fine for a few seconds than it started to decrease voltage slowly down to 230 volt or so. I started to change component by component and when just a few unchanged I replaced the dn2540 and issue solved, phuuu. Anyhow. Now the regulator seems to work alright, okey just 10 – 12 mA of load. With trimmer (200R) there is a range of 5V at 400V. Picture shows 400.0V and after 20 minutes the meter in “minmax” says average 400.0V within -0.0/+0.1.

Here's the latest offering from the fertile drives of my iMac Hmm, soundcloud cut out the first second or so?

Alex loves this ... he likes to listen to it before going to sleep.

Now the "Digital Concert Hall" of Berliner Philharmoniker is free for one month. Highly recommended.

Vinyl CFAe + SR202

I like the top transformer design as well. Reminds me of my first SRX build (on the right). Left one was my second where put trafo in the chassis.

The market is probably football players and execs that want something shiny on their desk. I wonder if it uses the same underperforming driver tech that the Sonoma Model 1 used? I'd like to see distortion measurements at 100db.

for the opening lines alone.. :)-

Woke up to this in the morning. It actually melted in the valley and on the east side mountians by me by mid day. Took the kids to the mountians on the west of the valley where it's high enough to keep b snow.

Yesterday I realized that, unconsciously over the years, I have bought almost all of Trane's discography on vinyl. Today touch this PS: Every day I enjoy more of my Pass Xono DIY.

Unfortunately I'm going to have a lot of time to go over my vinyl collection ...

Mating Call

A rare view from our back yard, snow in Southern California. On a somber note, the three houses under construction in the lower left are the result of the fires from last October.
