Hi all,

Re Pan American Sousaphones, i see some are advertised 52k, 68k etc what is the difference and how do you tell them apart, are they any good

Pan Americans are great sousaphones. They are Conn 14K and 32K sousaphones with a different name on the bell. Most of them are the smaller bell throat like the Conn 14K but I have seen a large bore one similar to a 38K. All great horns with .734 bore standard stroke valves.
