a late 60s/early 70s SB-12 has been on the LA Craigslist for 3 days for only $550 and it looks very nice and original. No guarantee that its still available, but if I didn't already have the earlier version, I'd be all over this one. Almost went for it as a backup..... This is too nice to let slip away. Please let it go to someone on the forum http://losangeles.craigslist.org/lac/msg/4159488569.html !!! edit !!! - I have no idea what speaker was used in this later version, so my earlier statement about this amp looking 'original' does not apply to the speaker. Can anyone add any info about the speaker?
