ok so I purchased a new house that had a hottub. The CD player (car type) mounted on the side was not working. I replaced the unit and that seemed to work fine. Then it would not turn on after a week. The player would turn on for about 5 seconds and then just flash on and off over and over. So at this point i think my 230v to 12v converter is shot. Anyone know a good place to purchase one of these?

This is what I would do if I had that problem. I would go to radio shack or maybe even perhaps wal-mart and get a standard 120V to 12V converter. I would then wire it up to the spa from one line wire to neutral and call it good. But, that is what I would do.
