A few weeks ago Don Teach mentioned a series of articles I wrote on the construction of the Wurlitzer unit valve that are posted on the Yahoo Wurlitzer 105 Group site, http://groups.yahoo.com/group/wurlitzer105/ From the emails I have received as a result of Don's posting, the articles seem to have a wider interest. As a result I have submitted these articles for posting on the MMD Archives site for those who are interested.
