No. No risk of frying the amp running it into an 8 ohm load.
You'll get 100 watts of power at this impedance. Add another 8
ohm cab, and you'll have 200 watts. Like the sticker sez, avoid
trying to run too many speakers at once :')

| I am NOT super-tech, but I think I can handle this one. And another
reason for me inserting my 2c is that maybe by spewing my opinion
out, a guru will either bless my answer or curse it and I'll learn
something.
Running the head with less than a 4-ohm load may actually fry the
amp. This is because as you approach lower ohm loads you are getting
closer to connecting the input to the output (no resistance).
If your amp has ONLY one speaker out labeled 4-ohms or two (both
labeled 4-ohms) then the amp is set up to handle a 4-ohm load and
putting ANY OTHER load on it is an impedience mismatch and will
probably affect the sound (from sacrificing power).
I believe that an 8-ohm load won't hurt you. A 2-ohm load, on the
other hand, may produce much smoke and look real neat on stage.
I am now definately in water at least up to my neck.

1252.3 | Extension Speaker Hookup | FSTTOO::GALLO | Ultrix Instructor | Thu Apr 13 1989 09:28 | 13 |

I suspected as much, thanks.
The amp has one speaker jack, but it has another hole for
a second jack. If I want to add another jack, how would I hook
it up so that two 8 ohm cabs = 1 4 ohm load? Do I just hook up
the (+) to (+) and (-) to (-)?
Thanks,
Tom

| also:
2 x 8 ohms in series = 16 ohms
for a 4x12, given 8 ohm speakers; hook two in series ( = 16 ohms)
and hooking the two series in parallel puts you back at 8 ohms
( series - parallel circuit )
