hey ed what is a step up transformer? do you mean the master volume? oh and the cab hookup.
there is a picture as you can see on the first sides of my thread there you can see the 2 input jacks with the selector
if you switch it to the right the cab runs at mono with selectable 4 ohm input or 16 ohm input
or you can run it stereo with the 2 inputs at 8 ohm.
Actually I miss spoke, I meant "step
down" transformer. That's what takes your wall current down to what the amp wants to see.
i bought the cab in order to have the right impedance of 4 ohm for the beta lead.
as i understand it the impedance is dependet on the number of speakers and how much ohm they run at. if you have 4 12" 16 ohm cabs...they oughta themselves down to 4 ohm because 16ohm : 4speakers = 4ohm speakers. or do i understand it wrong?
oh and another thing was mentioned by a friend of mine but i don't know if this could be the problem.
he said if the beta lead is from america and runs with 120 V...but the speaker cab is built in europe or china or whatever and possibly runs with 230 V....? he asked me if that could be it?
oh and what i wanted to know is... the power cable from the beta lead a three-wire cable or two? or four? three, right?
These are all questions you need to be asking the tech that you find local to you rather than a bunch of people on a different continent via a discussion forum.
I know you are frustrated with your amp, and it's obvious from the above quotes that you probably have
no business poking around inside your Beta.
What is
also obvious is that it's not a simple hook up issue; your amp seems to be in need of professional help.
So...
Again I'm going to suggest that you find a tech. It would seem that you CAN'T fix the problem; what do you expect to accomplish by continuing to ask questions about how
you CAN fix it?
You aren't going to get the help you need by posting in circles on this forum. Concentrate all of that energy on finding some who possibly CAN fix your amp.
I'm seriously not being an ass, and myself and others here are
really trying to point you in the right direction; but you keep posting the same things over and over as if something might miraculously
change, and that by simply plugging something in differently all will be well with your Beta.
That
isn't going to happen IMO;
possibly there is some misunderstanding in translation, but it sure seems like you have a sick Sunn on your hands and it needs a REAL doctor. Take your amp, cab, and probably most importantly the service manual to a QUALIFIED TECH.
If the
tech gets' "stuck", post
his or her questions here translated as accurately as possible.
Check back in once you get the amp and cab checked out by a professional; I'm certain that everyone here who has tried to assist you with your issue would like to see you get your rig fixed, and will be interested to know what the outcome is.
And, as I mentioned some of the more experienced techs here may indeed be able to assist a QUALIFIED TECH in getting your Beta up and running.
Good Luck!
