SOURCE: Technics SU-V2 keeps cutting out

An amp will cut out if the output protection circuit kicks in. This circuit compares output power against the preset level. Each channel has it's own, independent protector. There are calculations that can be done, but for a novice the rule of thumb is to "never use a speaker with a power rating less than the amp AND a lower impedance than stated". Typically using a 4 ohm load on a 8 ohm system is inviting disaster. Even if the system does not become a smoke generator, you might notice that though "louder", the sound quality is deteriorated. Many "audiophiles" often hook up some combinations of speakers to have "surround" without really understanding that the collective impedance actually changes (generally lowers).

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.

Technics su-g75 drawing/schematic? when hit power button fuse in power supply blowout.


Fuses blow when there's an overload. This is most likely caused by a semiconductor device(s) shorted. In amps this is often cuased by speaker wires that have touched while on power. The main culprits are the devices on the heat sink. If they are transistors then connecting an Ohm Meter accros the terminals of the transistor(s) (amp switched off) will show as if you have touched the test probes together! More than one device might have blown!!

Technics SU-G75 has no sound


Hello
when the resistors are burned,means that the transistors are damaged, or the power module is damaged.
and in your case its the power module.
Hope this helps.

What could cause intermittent no power to amplifier relay (RLY551) in Technics SU-V96?


Check the relay control transistors. Check the voltage at the collector and base of this transistor. Download the service manual to your device to get more details.

When I turn on my technics SU-V55A amp, the current drive does not engage. If I leave it, it normally comes on after a period of time. The amp then runs ok.


Check for dry solder joints especially on the main power output transistor.
A blown power transistor will stop the 'Current Drive' from engaging so if the problem you have is intermittent then it is most likely dry solder joints.

Hope this helps.

Does the SU-G88 AMP carry a remote control and can you advise where I can buy one from? Is the amp for sale and how much?


Search engines would reveal those answers faster than waiting for one of us to do it for you.

It DOES use a remote.

I have a technics su-v660 integrated amplifier.the voltage selector light comes on but the current drive light is intermittent .when the red drive light is on it works perfectly but only for 5 minutes then...


Unplug the power, open the case and try to locate some electrolytic capasitors is series with the audio at the channel with the problem. One of them must be blown.

In case of a problem or clarification, don't hesitate to post me a reply.
If you are satisfied, rate my solution with the "thumbs".

Hi, During moving we have lost the power leads for our hi-fi. It is a Technics, ST-Z980, SH-8038, SU-2980, RS-D190W, SL-P300. Can you help us with how we would purchase new ones. Cheers Grant


Hi Kitch,

Been there. If you have a goodwill near you, I have found the to be a great source for just about every power cable I have ever lost and needed to replace. Each one is usually about $1.00

Good luck,
Mike

Blinking light on front of amplifier Technics SU-V10X


Blingking Light usually means that there is DC appearing in output stage and is protecting Connected Speakers.
It can be faulty Output Stage (Bad ICs/Transistors/Resistors/Capacitors) or Faulty Power Supply.

Working on These types of Problem is not user friendly at all.

Advising to take local Authorized Shop.
