Jim, I believe you have the answer as my TITAN 425, S/N 425-00516 (labeled
as an export model) was sent back to TenTec for warranty work and upgrades
shortly after I purchased it new from AD0S. The TITAN 425 manual I have is
considerably different from the one I recently downloaded from Ten Tec's
obsolete manual page. The Tune and Load control setting I see on my TITAN
425 in actual service are closer to the initial settings suggested in the
downloaded (newer) manual than in the original manual.
73 es DX,

At some point, changes were made with the values of the capacitors
around the bandswitch in the output stage. There is one less capacitor
there than is shown in the manual. With the 3 Titan 425s I own,I've
always used the 80M settings for all of 80/75M. It works fine.
