Olddog75 has provided good information. A good source of strings is juststrings.com . You can make up your own sets. If you find that you don't like playing with equidistant strings you can add notches in the nut and bridge to play with a double melody string. The original tuning from the photo is melody string E, first drone E, second drone E, and the bass string G. If you are tuning to ddAD, the melody string will be d, first drone d, second drone A, and the bass string D. If you find the McSpadden set too loose or too tight you can calculate the ideal strings for your dulcimer using the Strother's string calculator but bear in mind that it tends to be a little "light" with it's suggestions. You can probably go up a gauge or two. http://www.strothers.com/string_choice.html
I hope this helps you. Let us know how the new strings work.
