Hi all. I have a nice T-1 with a 2x10 speaker arrangement that has been missing speakers for a long time. Getting around to fixing her up, but don't remember the OT secondary impedence. Should I be running two 16 ohm speakers in parallel for an 8 ohm load, two 8 ohm speakers for a. 4 ohm load, etc. Probably won't make a huge difference, but I'd like to get it back to factory specs. Thanks!
