I ultimately mounted my tank to the front panel, just like an original Fender Reverb Unit. As I mentioned, I didn't know it when I started, but Weber was still basically prototyping their kit and only had the chassis and board with the separate circuits on it. My OT is from a Champ and the choke is the same as a 6G15 which is the same as the BF amps. I sourced those and my parts through an amp tech buddy of mine (who has since passed on). He wasn't sure what to use for a PT so I contacted Ted Weber and he actually sent me a PT that was a prototype wind free of charge. The PT basically drove some of my build. It was too tall to mount inside the chassis which I think was the original intent (with the power supply caps in a doghouse like an original Fender). I had a custom cabinet made that was deeper to allow for the extra height of the PT. At the time I also couldn't find springs to suspend the tank from the four studs like Fender did so I contacted Ted again about the mounting (by this time he had a real kit) and he sent me that spring packet that you mentioned. I think their intent was to "float" the tank between springs and to cap them with the T-nut, except that I couldn't get any springs to work that way. I kept the tank on the floor of the cabinet loose for a while, and eventually found that Darren Riley had started selling the Fender springs from their '63 Reissue and was finally able to mount the tank like Fender did. It was a long journey and was surprised that there seemed to be so much of a ground noise issue on the net because mine is quiet. Hard to tell if I was good or lucky If you aren't familiar with the Fender mounting, there are four screws through the front panel. Their springs just thread onto those screws inside the cabinet and leave the end loop bent out at a little bit of an angle that extends just beyond the end of the screws. Another set of four springs hook to those loops and then go to the reverb pan. You end up with the pan suspended a little bit off the front panel of the cabinet and sort of in the middle of an X pattern between the four screws. Kind of difficult to describe but really quite simple in practice. No pics of that and I would have to pull the chassis of either my Revive or my original ''64 to take some. The Reissue documents on the Fender website might show the diagram and part numbers for mounting the tank.
