SOURCE: my su-g95 technics Stereo integrated amplifier

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.

Does a technics stereo amp su-g90 have a stereo to play music


This device does not have an internal tuner. It is simply an amplifier. The buttons on the front labeled TUNER - TAPE - PHONO - DAT/VCR 1 - VCR 2/TV are selector buttons for additional components that hook up to the respective connectors at the rear of the unit. If you want to play a radio with this device, you must buy a tuner and attach it to the tuner inputs in the rear of the unit.

On my Technics SU-G90 where do I connect the subwoofer


Some amps have a single RCA socket for a powered sub. If it has not got one of these then the amp has no output for a powered sub. If so then you can only use a none powered subwoofer, which will connect via the speakers of the amp, see the subwoofer manual for how to do this.

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.

I have a Technics stereo integrated amplifier SU G75. The cooling fan began making chirping noises then stopped. Now every time I turn the stereo on I get a overload message. Could it be the cooling fan...


It chirped because the bearings were worn out, then it froze up and isn't moving any air. Get it replaced. DO NOT run the unit if it keeps overloading or you will have a bigger problem.

My su g90 shuts off when i turn it up loud what do


Amplifiers get hot. The more you crank the volume up (or use extended for extended periods), the more current is required. When it gets hot, there is a fan motor (on the back), that should turn on. I believe your fan motor (brush) is worn out and therefore non-functional. Under this condition when the system overheats, it automatically changes mode to protect circuits.

Also note: if it works when you initially turn it on (cold) for a few minutes it should work fine...until it starts getting hot inside the case.
