Nathan Airchime RS5T prototypes

Nathan Airchime Prototype power chambers made to fit onto a Leslie horn, designed to be a replacement for RS and S chambers since the Leslie designs were easily fouled due to the silicone on the diaphragms were easily susceptible to tearing and caused the bell to go dead.
The prototype power chambers were designed to have the reliability and ease of maintenance of the Nathan K horn with the double diaphragm design. As I posted several times with these chambers, you can hear the issue with these chambers with the higher notes squealing. However this was mounted on my 1970 S5T-F. This is how they sound when it is operating normally. Quills like a Nathan, and the genuine growl of a Leslie.

Sounds like when I put my K chambers I modified to fit Leslie. My S5T sounded almost the same. SWEET!!
