I have a technics su g91 amplifier and speakers a and b will not work and i believe that it has to do something with the "over load" icon being lit up. I was wondering what that specific icon represented and what i can do to fix it?
I HAVE THE SAME PROBLEM WITH MY SU-G91, BUT THE LED DISPLAY DOESNT WORK EITHER, MY OVER LOAD LIGHT COMES ON WITH WHAT EVER I'M PLAYING "CD PLAYER,FM STEREO ETC." WHAT CAN I DO TO FIX MY STEREO AND HOW MUCH WILL IT COST ME TO HAVE IT FIXED?

Re: Technics SU-G91 OVERLOAD PROBLEM
THe amp has detected a problem and shutdown to prevent further damage. This unit has 2 amp pacs inside and one or both have failed. If you can solder, you can fix this yourself. The main amp pac is an SVI3206 and can be purchased online for about $60.
I just bought a Technics SU-G91, hoping to connect to my akai GX-230D reel to reel and speakers. do I need to get anything else to hear it, like a receiver/tuner? everything appears to be working or have I just hooked it up wrong?

The service manual :http://elektrotanya.com/technics_su-g91_sch_2.pdf/download.html. i can't see it on my ipad. Too fewapps:), read it and if you don't get it, just post it . Btw. Is the mute knob a real push button or which i assume a modern click one?
first read the instructions they contain some amazing information. I can not help you because I have no idea of what you want. The simple answer is to run the appropriate wire from the correct output to the correct input.
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.
The SU-G91 uses output IC's ( big black square things mounted on the silver heatsink inside the amplifier ). Once the overload light comes on, the output IC(s) are fried. It will have to go to a repair shop and the output IC's are expensive $80-$100 each !!
