It's simple I had the same problem , all u need is terminal compound. Here is what u do , open ur receiver inside u see huge heatsink and RSN3305 AUDIO MODULES H are on the heatsink rite , so u do this umscrew them off the heatsink and rest of stuff that is connecter to the heatshink , then when everything unscrewed from heatsink , then u umscrew heatsink its self from the unit , pull the heatsink out and put terminal compoud on it put nice amount and make is nice and smooth its urfinger do that in spot the audio modules were located , then u look and the back of the audio modules and apply terminal compound to the back of them also and also smooth it out with ur finger , make sure its all covered up and smoothly , make sure u didn't leave not even a tiny peace not covered , and after that put it all toghwter , the reason it happens after many years of use the compound that was put there by technics at factory probobly dried out by now and audio modules starting to overheat due to lack of compoud comecctiong to the heatsinck , after that process it will work as new , till terminal compound dries up ... It's simple fix and it will work just as it did out of the store

This amp uses a large IC for the final amp stage (RSN3305). This is the likely part that is defective. It is possible that the voltage regulator circuit is defective as well. Without taking measurements inside the unit, I can not state for sure. The part costs approx $75.

Let me know if you need more info.

Su-2760 will not work. gets a flash of power, turn off

Sounds like the safety circuit is tripping cutting off the power. Most probable cause a short circuit on the main power amp board, causing an overload.

The clicking sound will be a relay for the protection circuit. That could be faulty, but first check out the main devices on the main amp section. Those attached to the big heat sink. If you see a single IC amp that could well be faulty.

My technics amplifier su-g86 started by clicking off and leaving no sound. Now it turns on, but has no sound. The speakers are hooked up and everything else is fine. It just clicks off periodically and...

Most of the time this problem is caused by bad solder joints.
All the units I have repaired all that was needed was to reflow the solder joints.
The most common place is the leads of the hybrid IC.
Usually there are very very fine cracks which can barely be seen with a good magnifying glass.
I usually go ahead and resolder most of the solder joints related to the output section.
Basically the mechanical stress of the heating and cooling causes this as well as the manufacturer trying to use as little solder as possible.

Hope this helps,
