Sansui 771
A whisp of smoke came from this receiver on the weekend and I am nervous to
use it now. It used to take a second and there would be a click, then it would power up. Now the click is not there, but it still seems to work fine, but static comes over the speakers on power up. The resistor that smoked is next to the little plastic switch looking thing on the right side of the board. Ya think it can be repaired or is it toast-tea-toes...Thanks. I don't know my way around this stuff at all. Ev |

Hence, no click and you get static at startup. Just my 2 cents as I don't work with audio electronics |

I agree,
Audio output relay circuit, contacts either welded on, or timing circuit has bitten the dust Paul |

Oh, btw, ya figure the old fossil can be repaired at a reasonable cost or is
it ripe for target practice? Ev "Ev" wrote in message ... A whisp of smoke came from this receiver on the weekend and I am nervous to use it now.

They may be able to give you a better informed opinion. Repair will depend on someone having the schematics or repair manual, the availability of parts, etc. However, the kind of problem your receiver has should be simple to isolate and repair from a technical point of view. Good luck. |

Parts expense should be no more than $10 AUD, repair will be around $80 AUD
