About Us — Feedback

My only feedback about this site is e-mail from the readers and the statistics from the web hosting company.  Several changes have been made in response to your suggestions. The site is being simplified.  Pages that were visited infrequently have been combined or eliminated. Many pages are being updated to answer recurring questions. The automotive pages (mostly pictures) have been expanded due to reader requests.

We will begin selling some of the “stuff” (over 100, 000 tubes and other treasures) that is in our warehouses on Ebay (Ebay id = tubelab*com) to offset the web site and development costs.

I have limited time to devote to this web site since I work a full time (45 to 60 hours per week) at a large electronics company. Many of my friends who I have worked with for 20 to 30 years have been laid off. I must make my job priority #1. Work on this site happens in my spare time. I have a list of requests from readers for specific projects. Distilled down from that list is the list of my next few amplifier designs. The next one will be a plug and play SE amp mentioned above.
