## Questions & Answers

**Q: Hi Can I wire just one or several coils of thick copper wire to this toroid transformer to make a step down transformer?**
A: You could make a stepdown transformer using two steel bars and coiled copper wire.  The resulting step down voltage would be AC the value of which you would have to calculate from the properties of the copper wire.

**Q: would this be suitable for driving a 12ax7 filament?**
A: Should work OK.  The output is 12V and 2.5 amps, so should be adequate power.  doug@bulbwizards
