SOURCE: 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

SOURCE: i have a SU-G75 Technics stereo intergrated

Hi grayjt1963,

Based on the symptoms that you described this problem is caused by either of the two components. The most likely reason why you are getting no sound at all right now is the protect mode which your amp is in right now with the outputs turned off to prevent further damage. This unit have an AMP-Pac for the final stages that may be defective. The part number is RSN3306. This is the most likely part and can be purchased for about $60. Also inside is another AMP-Pac for the center and rear speakers (SVI3204B) which runs about $58. Either can cause the symptom you describe.

Hope this helps.

Thank you for using FixYa.

Technics SU-G75 overload


I have the same problem..it will be required to remove the board and resolder "cold " solderings... None of above solutions have been helpful, but "you get what you paid for"..and I completely disagree...even if required, remove ALL audio power managing circuitry and replace this expensive original design with TI´s Integrated chips..using PWM technology..unless you want to go back to L6, ot Kts tubes..
