Durand Tonearms Balancing nature and technology

• Still confused about cartridge loading? Jim Hagerman can help

• A lot on step-up transformers (SUT) can be learned from David Slagle. Read his forum on the topic.

• If you're interested in loading your SUT, at some point, you'll need to know the formula to calculate the result of resistors in parallel; here is how to do it (see Parallel circuits). If you have an iPhone, there's a handy app to calculate resistors in series and parallel (ResistorCode).

• David Slagle addressed the question of phase response in SUTs on his forum.

We like analog, but we've noticed that there seems to be life on other planets as well:

• The world of Lynn Olson, circuit designer; one of the most knowledgeable audio people out there

• John Atwood's ClariSonus is a good source of in-depth reports on many audio subjects

• High End Audio: Arthur Salvatore's site. If you haven't heard about it yet, check it out. Tons of information and reviews on equipment from now and the past

• Resources on tubes:

^ Frank's Electron tube Pages has a solid collection of tube data sheets; also diagrams and photos of tube pins, etc, and an interesting page on tube numbering system

^ Help from John Broskie on designing circuits in the Tube CAD Journal

^ For further help, check the DYI Audio forum

• Marcel Wanders, one of my favorite designers. Check out his Personal Editions (in the Products section) and his Interiors.

• Lebbeus Woods, architect extraordinaire. I discovered Woods through his "War and Architecture" book from the early 90s, which contains projects for reconstructions of cities destroyed by war (Sarajevo, more specifically). His work has remained a great source of inspiration. His blog is an amazing reservoir of provocative ideas.

• my favorite photographer (ok, he's my brother!)

• A big thanks to our woodworker extraordinaire, Curt Hart. Curt makes the armwands and boxes for the Talea™ and the Telos™.
