I am posting this minor update (from a hotel room with free internet) to add the pictures from the 2006 Mopar Nationals including an entire page of pictures of the 2008 Dodge Challenger concept car. It was announced that production of this car will commence in April of 2008. I have done some minor reorganization of the site to make room for more pages in the future. Everything is still here, although some pages (and their links) now have their own sub page. I have been working on the assembly manual for the SSE amplifier. My return (and the manual) has been delayed by car trouble. Try to find an oil pan for a Volvo in rural West Virginia.
The break in my work schedule lasted for 7 days (I knew that it was too good to be true). The SSE boards are in and three amps are already up and running. I can build these boards in about 45 minutes each, they go together real easy. I am already working on the construction manual. I have gathered about 500 pounds of transformers which will all be tested and the results posted here (two transformers are already done). I will be out of town for most of August, so there will not be much activity until September.
I finally got a break from my relentless work schedule (it won't last) so I have been updating the web site every night. I have added (or finished) several pages in the Tech Pages and Tested and Proven Circuits sections. These pages were created to explain some of the experiments that began as a thread on the diyAudio forums. Some of the material is directly cut from my contributions to those threads. Some additional material has been added.
The SSE section has been updated, and will continue to be updated as more info becomes available. The PC boards are on order. My amp has been stressed tested in several ways, including me playing guitar through it, and plugging it into a Variac and cranking the input voltage to 135 volts while playing rock music at full volume! It is still going strong.
I have added some text and old pictures to the Tubelab SE assembly manual. I sold every assembled board that I had during the time that I was too busy to build any (the past 4 months). The pictures (text too) for the checkout and bias adjustment pages were lost last year. I have finished assembling a new board, and the new pictures will be shot this weekend. I will add them to the site ASAP.
