That you for the info!
I tried installing the 721TS chassis and knobs but quickly ran into a few problems. First, the speaker definitely needs to be removed as the chassis will not slide far enough into the cabinet.
Secondly, I'm not sure how to install the channel dial plate. It looks like I need to unmount the cabinet font and it has two wing nuts just like the TS, but something is holding it firm at the bottom.
I'm guessing there may be a screw hidden under this brass piece ? Perhaps there are some screw inside ?
