Hey guys, I've got a GNX3 I've had for a couple years now. A couple months ago the power supply went out, so I ordered a new one. Now, it powers up, but the sound does not work. When I put it on the tuner I just get -------- I seem to recall that a second or two after you switched it on, you would here a distinctive "click" of a relay. Am I making up that memory, or does that happen?

Hi PepeSilvia,
1. If your new power supply does not identical to the genuine PSS3,
check whether it is suitable {Vout = 9VAC, I out = 2.1A minimum,
polarity: N/A (AC output)}.
2. If power supply is OK, do so called “Factory Reset”.
3. If this does not help, the GNX3 requires repair. -
Hey doc! I thought I spec'd my supply correctly, I skimped a little on the current, only got a 2A supply as opposed to 2.1A, but I'm not sure that makes a difference. Also, it's DC (didn't realize the original was AC) but that shouldn't matter because it's rectified, right? Is it possible that it being able to power up and act like it was working normally, but not be able to pass sound would be a power issue? I tried doing the Factory Reset, to no avail.Comment

DC power supply is absolutely unsuitable.
When AC power supply is used, positive and
negative DC voltages of 12.6V amplitude
(~140% of AC voltage) are produced after rectifying.
These voltages feed corresponding regulators
to produce stabilized positive and negative
voltages to analog circuitries.
When DC power supply is used, only positive
voltage of 9V is produced.
For this reason your device cannot to operate at all.
Replace power supply to AC.
Amperage 2A is sufficient, but always desirable
to have a margin. 2.5A is preferable.Comment
