What causes the sound to cut for a few seconds?


Hi i just would to know if you did try to connect your TV by HDMI to test if your optical output of your reciever/amplifier have some problem. In second time yes maybe you can have an overheating problem, just take a look at your grid and maybe a clean-up will be necessary. I don't think your amplifier have a fan.
Don't hesitate to contact me here in this post. have a nice day.

I have a technics hifi su-ch900 everytime I play a cd or cassette or have the tuner the sound cuts out when its slightly loud, on low volume its fine. I have checked the cables and they are correctly...


I found a link to a CH900 that switched off completely.
If you are not a technician, please don't open the amplifier.
But I think it will be a simple repair. It is not the same problem, but it looks a little simelar.

Tile saw not cutting straight


Sometimes a blade that is set deep enough will walk in this manner, especially if it is a thin kerf blade like the MK Hotdog blade.

Also, a blade which has worn unevenly will do this too.

Technics amplifier switches off


1-keep good ventillation around and do not block any ventillation holes with any thing.
2-check your connection cable in good condition no touching of inner conductor with any chasis.
3-check your loudspeakers and apply them to the system one by one until you find the bad one(which make the problem if it is bad)

Technics amplifier su-v98, cuts off at 22-24 desibls


The most common cause of this is defective coupling caps inside. These allow some DC voltage to pass through to the final amp stage. This DDC voltage is detected by the protection circuit and the unit shuts down. This unit will require service. Please note that this should be a simple and inexpensive repair. The cost should be less than $10 for parts.

Sound cuts when volume is turned up


check that power amplifier rating(how many watt)must be more than total speaker rating by 20% at least..
exampel:if speakers watts are 100 watt-amplifier watt must be 120 watt.

Speakers cut out after about 10 minutes.


Does the system perform normally- as long as it works? If yes, then the Amplifier is at fault. It cannot be the output Transistors or IC, as the sound is coming from both channels. If you know solid state servicing, I advice replacing all the electrolytic capacitors in the Output stages of the Amplifier. Over a period of time these El Caps dry out, and cause headaches.
