Hey guys, just picked up a Silvertone 1333 on the cheap. Sounds pretty good, but speaker is rubbing the voice coil, I know that sound a mile away. The clearance between the 6v6 power tubes, and the magnet is pretty damned small. Pics included. Does anyone have any info on these? Maybe stock speaker, a replacement that fits? It's a 12 inch. Also, any way to daye these? Codes on the transformer are unreadable.
