It sounds like the switch might be broken. It might need to be replaced.

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: Technics SU-V460 Amp Problems

Problem with older equipment is that mechanical switches corrode. Try some tuner cleaner on switches. One side cutting out may require the speaker leads (inside the cone of speaker) to be re tinned. Old speakers and lossa mileage cause solder to break up into powder. Re tinning the flexible link (looks much like a wick) allows that electricity to get into the speaker coil. If all else fails those old TV repair shops actually do have real techs that can fix it. Not like the current Geek Squad type of replace replace reboot replace type of tech. Good luck. Ed

Technics su-v460 amp wont turn on. no power light


Check an look around for fuses. Broken Power switch? Mains Transformer failure?

Amp won't power on


It sound like the main power amp has failed. Look at whatever is on the big heatsink as to the cause. As with any device from "friends" it could be that someone has tried to fix a fault and made a mess. So look carefully at the soldering to any of it's parts.

How do I hook up a stereo reciver to the technics su-g91


I assume you want to use the SU-G91 as a power amplifier to drive your speakers. If your receiver has connections for inserting an equalizer (may be labeled pre-amp output and power amp input), remove the jumpers between the pre-amp and the power amp, then run cables from the pre-amp to the SU-G91 inputs. You can have an equalizer between the receiver and the integrated amplifier.
If this is not available, use the recording output (for a tape recorder on older receivers). Note that the volume control on the receiver will be bypassed with this connection.

My su-g95 technics Stereo integrated amplifier wont play any noise. and when i adjust the volume it makes a popping/crackling noise. i am 100% sure all the speakers were hooked up correctly.


Well it sounds like your amplifier IC's are working correctly since you are hearing that pop. I have the same amplifier and every 10db increment it pops. Have you tried every input? Possibly try starting at a low volume, plug an RCA plug into CD or any other input, and touch the center prong of the other end of the cable. You should get a 60hz hum if your in the USA, otherwise it will be 50-55hz. Regardless it should make noise.

I have a Technics SU-V460 integrated amplifier, and the left channel (speaker) keeps "dropping" out . I have to turn the volume right up in order for it to "kick" back in. Would this be...


There are three possible problems with your system. The first, and cheapest to fix, is that the wire connecting the left channel is faulty. To test this, unplug the wire from the back of the amp and put a new one in, then play some music BEFORE putting everything back into it's respective place. If the speaker doesn't cut out anymore, problem solved! Speaker wire is very cheap too. If the problem persists, try connecting one of your other speakers that you know works to the input. If that speaker cuts out as well, then the amplifier is the faulty component. That will cost some money to repair (between $50-$150 depending on where you go, excluding the price of a new amplifier). If the speaker you know is not faulty works when plugged into the left channel, then the only other option is that the original left channel speaker is faulty. This could cost between $25-$100 to get repaired, excluding the cost of a new speaker. It will not be as costly as a new amp, but will definitely cost more than a new speaker cable.

Technics su-Z750 Intergrated Amplifier stays in Standby


HI...
This happens when one or more components in the power amplifier section has failed.

The protect circuit keeps large DC voltages off the speakers.

The only thing you can check for before finding a tech is that the speakers are firmly connected at both ends. If they are ok, you need a tech

PLease rate my help if this helps

Technics SU-V460 Amp Problems


Hi There, you need to eliminate all the connection and surplus items around the SUV-460 amplifier to determine if its the amp or not..

That is disconnect every thing then connect just the speakers and an input to the amp like a CD player or radio input. Then see if the amplifier plays OK thru the speakers on both channels and the balance control works fine....If it doesnt then the fault is inside the SUV-460 but if it all works fine than start reconnecting theemixer panel carefully and recheck all your cables and connections. Its a process of elimination to determine if its a "Box" fault or a cable fault...

Cheers From YUBEUT
