Getting things back to the way they were
Well I have not fixed the hard drives on the 8500r so I just moved everything over to a small Raq3 for the time being. Its a lot slower so please bear with me as I move the files back over.

Peter Daniel Non OS TDA1543 USB DAC
My latest build has been a pair of DAC’s. I was able to get all the parts from Digi, Michael Percy and
Parts Connexion.
Peter Daniel swears by the Black Gate N series capacitors in
all places but since they have been out of production since 2007 they are
getting just about impossible to source. Michael Percy has stock on most sizes
still but 4.7uf’s are non existent across the globe. I really did not want to
spend $300.00 just on the power filter caps so I went with Nichicon Muse non
polar BP’s on the filters and the output couplings. The rest of the caps I was
able to get Black Gates N’s. I did splurge and went with Caddok resistors on
the output stage. I may have to get some Teflon coupling caps to really get the
benefit out of these but that’s for tweaking in the future.

Tube Database
I finally got around to entering most of my tubes into my database. It was quite a bit of work to get things set up but now once its set up I can enter in tubes as I order and buy them.
The database can be seen here
Check out the "List All" and the Search function.
The structure is based on OpenDB and I wrote all off the categories, item structures and types. Since the program was originally written for collecting movies it was quite a bit of changes.
Since I wanted to have pictures of every tube that I entered. I had to come up with a simple way to take and upload pictures to my web server. I solved this with a wi-fi SD card from Eye-fi. The SD card goes in the camera and when ever you are near your wi-fi network it automatically uploads the pictures to you computer. Unfortunately this only works with windows and Mac. I made a folder on my windows box for the pictures to upload to and got a script to ftp any file dropped into that folder to my webserver. Now when I want to enter a tube I take the picture of the tube and just enter the link to the picture in the form I made. It works pretty smooth and you can enter ina tube in under 30 seconds.
If you would like to try this for yourself let me know and I will help you.

Adventures in Open Baffles
I have finished my first set of Open Baffles. So far they sound pretty good. They were fairly simple to make and the whole project was less then 40 bucks.
Click the picture to see how I made them.

833A making mad light
Shot of my 833A lit up. Want to make a serious SE amp with a set of them. Got this one for a deal so I was just testing the filament. Oh and in case you are ever wondering if you can fire up an 833A with a ATX power supply even if its rated for 20A. No, no you can not. It causes lots of smoke, smell and very little else. Anyone have a spare ATX?
