Numerous internet searches have turned up damp squib, so I'll inquire with thee. I yoinked this 15 from a Leslie that was parted out after, only I kept this for a future project. The time has come to thin the herd of projects that I will never get to so before I toss this old beast I'd like to know more about it. Pics! It certainly resembles a CTS, the likes of which were known to be found in Ampeg B's (and probably many others). It sounded perfect in the Leslie, so the repair seems to have been well done. No buzzes or anything. Any ideas? Thanks!
