SOURCE: 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.

SOURCE: Technics SU-G95 Amplifier and no sound on left speakers

Usually this is a defect in the output amp IC. If you have no experience with repairs of these types of units, have it checked by a service shop. If the output AMP IChas failed, it will cost about $75 for a replacement. This unit uses an RSN3306P IC .

I think I've blown my internal fuse/s on my technics amplifier model number su-ch7. How can I fix myself?

This will have the service manual. If you are not experienced in this type of repair, it will probably be far less expensive to take it to a repair shop.

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.

Technics Amplifier SU-VZ320 plays sound for a while and just cuts out sound. Tried switching off and on but no sounds comes through. Leave it off for a while then turn it back on get sound then cuts out...


puede ser un problema con la fuente de poder de la planta,con los parlantes,con los cables y terminales que conectan los parlantes con la planta ,puesto que la mayoria de amplificadores tienen control de temperatura y al sobrecalentarce se apaga por protecion y por eso ensiende por un rato y despues se apaga, por favor revice que los parlantes y los cables con teminales esten bien y no esten aciendo contacto

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.
