I do remember waaaay back that a friend of mine ran an 1104C. What I remember was it sounded very good, but could also be made to be punchy like a D104. So you can have a nice mellow sound for local talk, and the punchy sound for DX. I always thought they were a little hard to come by, but you never know what you'll find on Amazon or Ebay these days.
I never had a 10DA head for my Tug stand, but another local used to run one back in the old days, and it was a pretty mellow sounding mic. He ran his on a Tram D201, and the tubes may have contributed a bit to the mellow sound.. who knows. Since you already have a 10D head, I would definitely wire it up and see how she does.
