This trombone has been in my family for a long time. I’m looking to sell it since I rarely (if ever) play a bass trombone anymore. It has a spring at first position to ensure fast action when moving the slide as well as threaded rotor valves to have seamless and silent movement. This trombone was made in 1969 which is known by collectors as one of the best years for the Conn instrument manufacturing. The indication for this is the M one the serial number of the bass trombone. The 73H is similar to the 62H: it is a bass trombone, dual rotor. The difference with the 62H is that the 73H has a regular brass bell as opposed to the 62H’s red brass bell, and the 73H has the main tuning slide in the bell, whereas the 62H’s main tuning slide is in the slide. The 73H has the same #5 (0.562) bore as the 62H. Like the 62H, it was produced from at least 1968 to 1972, and was probably discontinued sometime between 1973 and 1980. In a 1969 ad featuring the 60H, 62H, 71H and 73H, Conn says: We have just created the 4 finest bass trombones in the world… What Conn said in the 1970’s. Has special double rotors to F and E. The double rotor bass trombone with second rotor E tuning eliminates the need to pull the F slide to play low B, and maintains the advantage of have C and F in 1st position. The instrument not only has all the advantages of single rotor bass trombones pitched in Bb and F, but also by using the overtone series of the E valve, the player has three horns in one: Bb, F and E. The double rotor bass trombone with Bb open horn, first rotor F tuning and second rotor D tuning is the most practical combination for all types of playing the bass trombonist is likely to encounter, and simplifies the most intricate passages. To play a chromatic scale, the player need not go past the 5th position. Lustre-Conn finish over polished brass with nickel trim. Cylindrical bore 0.562. This Trombone is a great option for anyone looking for a career level bass trombone! Note: Mouthpiece not included.
