I'm getting one here in Italy, probably next week; I know it's not a C11 (which i do own), but for 300 euro, mint condition, perfectly worked on, I consider it a bargain! And it will be the fifth McIntosh preamp in my collection!
Not many C24 here, forty years ago people seemed to prefer C22 tube preamps, or C26 and C28 SS preamps!
