Question about Yamaha AX-396 Amplifier

2 Answers

Pathos One MK II Integrated amp.

Hello.
The amp works but I ear about ten times more the humming of the 60 HZ on the left compare with the right channel, it also has difficulties with the high pitch sounds like female voices in classical music or instruments like the flute. It's not the speakers or the source. The high frequencies lose clarity and become annoying to the ear. A technicien told me that it would be very difficult to localise the cause of the problem.

If you swap which terminal each speak is plugged into, does the problem move to the other side?

I wonder if there is a power cable that runs very close to your speaker wires? You can get hum crossing over that way.

What is causing my 1967 Hagstrom II guitar pickups to have an RF interference hum and how can I eliminate it?


I would say your first impression was correct, even though the additional image you submitted is impossible to view clearly. Single coil pickups are particularly vulnerable to 60 Hz EMI (50 Hz in some parts of the world) from AC power lines, and depending on the values and lengths of connecting wires can be surprisingly good antennas for broadcast radio stations or CB transmissions 8^0. This is managed with proper shielding around the electronics cavity in the guitar body, and sometimes, particularly in North America, by connecting the the ground side of the audio circuit to the bridge, which then connects the ground to the strings and then the human body through the hands, allowing it to act as an impedance sink. Best practice has all wires carrying audio signal surrounded by a mesh shield connected to a common point audio ground.

No just the cartridge perhaps! First disconect the wires to the cartridge. With the amp on. Touch the end of the wires one at a time (don't worry you won't get a shock). On two of the wires you should hear a hum on each channel (one for left one for right). The left channel should hum. If it doesn't it's not the cartridge, but either a faulty lead or the left phono pre-amp is faulty on your amp. Test the amp by putting the right in the left channel.
If the left hums the cartridge is faulty.

Missing power cord


HELLO AND NO YOUR AMP SUPPLY IS'NT THE RIGHT AMOUNT YOUR CORD ONLY SUPPLIES 2.5 AND YOUR T.V. CALLS FOR 5.2 IT'LL RUN YOUR T.V. BUT THE REASON IT WONT WORK IS BECAUSE YOUR T.V. WILL PULL 5.2 AMPS AND YOUR CORD IS ONLY RATED FOR 2.5 IN TIME THE CORD WILL BURN OUT OR GET HOT AND CAUSE A POSSABLE FIRE.

Sunfire Mk II hum (different from greekboy post)


I had this issue a few years ago and the power cable from one of the inner terminals had come loose. It was still touching but whenever the sub would really pound it would jump off the connection and then reconnect causing it to hum. It was the most annoying thing ever so I finally pulled off the amp plate (super easy) and you could clearly see the loose wire. I had to use a good soldering iron to put it back on since it's a pretty fat wire. If you're not under warranty anymore then pop the back off and see if that's the issue.
