Re: Having problem - general Q about wattage, heads, and cabs (bass related)

stratrhythm - 10 Feb 2005 18:02:30

Tube amps certainly "sound" more powerful than transistor amps, but
people are still arguing about why. Neither formula you quoted (five
times or the ohms/watts ) works. But that doesn't really help....
If you're sure it was an "electrical noise" it probably came from
the amp itself. Speakers are passive devices and can only
make "mechanical" noises. But remember, 200 watts tube is a BIG amp
by ANY standards and can blow your speakers...almost any speakers,
particularly if you're foolin' around with the EQ that comes on that
amp.
My advice to you is to call Mesa and talk to a real person in tech
and describe your symptoms, and see what they've got to recommend.
