My new computer is finally operational,
I have been on the road for almost every weekend so far this year. Most of this web update was written from the passenger seat of a car on my laptop. Some pages are still incomplete, but I decided to post what I have since it has been a while since the last update. Most of the SSE manual is complete, except for the wiring diagrams, parts list with vendor part numbers since I don't have internet access in my car, and the assembly pictures of my latest amps, since I haven't been home to take the pictures. I built (and documented) the Industrial amp shown above in December, and haven't had time to listen to it since then. I haven't touched a soldering iron yet this year either.
I have not yet figured out how to set up an internet shopping cart on my web page. It must be set up interactively on the server, and again, I have not been home to figure it out. I plan to begin listing the PC boards on Ebay as soon as the parts lists and wiring diagrams are complete. If my current work schedule does not change, this should be in a couple of weeks. My Ebay ID is Tubelab*com. There is nothing posted there currently.
I have fallen far behind in answering email. I thought that I could catch up over the holidays, but my planned two week vacation turned into 6 days off from work. I spent one to two hours per day answering email. During this time I received more email that I answered. I still have several hundred emails in my in box, and 5 or 10 come in each day. I have come to the realization that I may never catch up. All email from purchasers of my boards has been answered promptly. Much of the other email concerns PowerDrive. The PowerDrive cookbook page is not finished yet, but I have posted the first part. More email concerns the availability of the PC boards. They will be available shortly, and the ordering info will be posted here. Email that requires considerable time, like those asking me to design a special circuit, or modify or test an amplifier that I have never seen often does not get answered. I simply don't have the time to design one off circuits until I get caught up.
Many questions (e-mail and diyAudio forum) relate to the PC boards. I get questions that ask about the "SE board". I have no way of knowing which board you are referring to, since there are now two different SE boards. I have also received questions asking how to wire a DHT into the SSE board and vice versa. This is not really practical. Each board was designed and optimized for the type of tubes listed in the assembly manual. I simply do not currently have the time to assist with a custom design or application for these designs.
The most popular questions are," Where can I get a board" and "When can I get a board". I plan to offer the boards directly from an online ordering page on this web site. I have that option on my current hosting plan. I may also offer them from an Ebay store. I will do this as soon as the assembly manual is finished. Most of the manual is finished (all of the fun amp building stuff). I need to finish processing about 200 pictures and organizing all of the text. I have about 3 weeks worth of work at my present rate, but I can not predict the demands of my full time job, which have been considerable, and require 8 to 10 hours of sitting in front of a computer per day.
The progress will be posted here on this page, and ordering information will be posted here as well.
