[Trombone-l] Conn 73H bass trombone questions

[Frank Doting]

I have recently acquired a very nice original condition Conn 73H bass trombone.  It is the Bb/F/E configuration with the original paddle arrangement.  The questions:

1)  Can it be easily converted to the Bb/F/D configuration to be the same as my Conn 62H?
2)  Have some had the paddle setup changed as the double paddle use requires a lot of pressure.

Although it is a closed wrap instrument, the performance with the F paddle is OK in my opinion.  Comments on this issue?
