I am aware that z scale should be only 8-10v, so what I want to know, is how hard is it to convert or change an old controller? Is there a resister or step down module i can buy? Any suggestions?
You might try a voltage regulator. Common fixed regulators are 5 v, 9v, 12v, and 15 v. I'm not sure that there is a fixed 8v regulator. but a 9v one may work. Also there are variable regulators that you could set for 8v. I recommend mounting the regulator on a heat sink, since it will get hot in operation. One source for voltage regulators, heat sinks, and any other electronic components, is www.allelectronics.com
Use the "Search line at the top to pull up "voltage regulators" and scroll down to find a 9v regulator.
