Hi,
I've got myself an OzAudio Q-Mix HM-6 headphone amp from the US, and it wants 120v. I'm in Australia so running on 240v.
I know I could just buy a step-down transformer but I would prefer to replace the CT transformer inside the unit.. my only problem is I don't know the output voltage of the original one in there, and I've no way of testing it because I don't have a step-down.
The unit uses a whole bunch of NJM4560L op-amps, and the datasheet for that says they run on +/- 4V ~ +/- 18V - so would it be safe if I buy a 240v - 15v transformer to replace? Would it make a difference if I replace the original with a 9, 12, 15 or 18? I don't think there's any other active components inside the unit.
I've emailed OzAudio and asked for the specs but have been waiting for a reply for a while
Thanks!
