## Questions & Answers

**Q: Is this the older model ha540 or the ha540 mkii?**
A: The MK2 is the new one I would bet that all are the MK2 version, but that would be up to the individual seller.  Looks like Amazon is not very good at updating the listing.

**Q: Is this amp for operation on 110 to 240 Volts ?**
A: This item comes with a universal voltage AC adapter.  It has input voltage of 100-240v 50/60hz.

**Q: What's the output power of this? How many milliwatts or watts?**
A: Max. Output: 500 mW/side, 1 W/Stereo ( @ 16 Ohms )

**Q: Is this pure tube, with no transistors in the audio path?Thank you in advance!**
A: I forgot to mention, this a great sounding amplifier.  I would highly recommend changing the tube.  I changed the original tube with a Mullard tube but am now using it with a JJ ECC803 / 12AX7 Long Plate Gold Pin Vacuum Tube and it sounds great.  The tube does make a difference.
