Can I use a Step-Down Transformer to lower the output voltage of an AC adapter?
I have an IBM LCD monitor that I got on the cheap from Ebay, the issue was that it didn't have a base or a power supply.
Big deal, I thought because the plan was to wall-mount it and I had 6-7 old ac adapters lying around that would have roughly the same voltage and amperage.
So, now that I got it in the mail, I find that it requires a 12v 3.0 amp adapter. Unfortunately, all the adapters I have that provide enough amperage are all 19V or higher.
Back to the question, couldn't I just add a transformer inline with the output cable to step down the voltage to a level that will not fry the monitor?
Where could I find a step-down transformer that small?
The main point of this was to figure out a way to do it and avoid having to buy the adapter outright. There is a good level of satisfaction knowing that you were able to avoid spending money by doing things yourself.
