I bought SIG 12S off of a forum member and I've got to say it fits the 1482 like a glove (thanks toykat). I previously changed the speaker baffle in my beater '67 to 3/8" birch ply and put 4 & 8 ohm jacks on the OT taps to prepare it for just such an occasion. I slapped it in a few days ago, threw in a fresh pair of RCA 6V6GTA gray plates, put a very strong testing Sylvania 12AX7 long plate in V1, plugged in my Tele and fired it up. I was immediately bathed in glorious tweed toned crunch and couldn't put my guitar down for more than an hour. Okay...it's established, I really like these speakers in a 1482.
