Sound problem with Technics SU-G91 amp

I have the whole 5 piece home audio system which was bought new in 1992 (I think). This system is wonderful, everything plays beautiflly, but the sound will not adjust. All of the sudden it just locked in on a certain spot (about 78dc) which is pretty loud, and it will not adjust up or down. The remote will not adjust the sound, nor the knob on the amp. Any suggestions? I hate to disgaurd this system, it plays so well, if the sound was adjustable it would be perfect.

If I understand your posting correctly, the amp works using the Aux In connectors but not using the VCR1 even when VCR1 is selected correct? If that is the case, there is an internal electronic switching IC (TA9263 I think) that may be defective. This is not a complex repair and can be confirmed easily by any shop that does audio repair. They will trace the incoming signal with an oscilloscope to the IC and see nothing come out when VCR1 is selected. The IC costs less than $10.

I have a Technics SU-G91 amp that is stuck in overload even with no input. I have tried giving it a quick blast of air to dust and still nothing. All help is appreciated!!


Your Technics unit will remain in the overload (protect mode) state until component failures have been corrected. The output stages and/or associated components may have failed.

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.

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.

Keep me posted.
