I own a '68 bottom cab with 30 waters (102 014 cones and NO labels) that I bought last year. I took the back off the cab to do some investigating this weekend because I intend on restoring it. It's been recovered long ago, caster cups filled, piping channels filled as well. The wiring is series-parallel as it should be, solder connections are in good order, and all speakers are functioning and sound awesome!
I'm reading 8.2 to 9 Ohms on the speakers individually while they're still soldered in place. I'm taking the readings with a nice Fluke 787 behind the speaker tabs on the braided copper wire going directly to the coil. The reading fluctuates at the jack from 10.5 to 11 Ohms. Shouldn't this be a 16ohm cab? Did they make 8 ohm cabs in '68?
I'm using the cab with a early '69 metal panel SL and a 12,000 Metro build and have always used the 16 ohm taps on the amps. Now I'm wondering if I should I be running my amps at 8 ohms instead of 16 or is it safe for either? (especially the '69 SL). Suggestions?
Thanks,
Robert
