Amplifier: Sansui 8080db problem. Please help

Hello. I have a problem with my amplifier. The dials and meters are working correctly except the amp meter is measuring no output. There is no sound even though my speakers are plugged in. What could have caused this?

dust.

I don't recommend fiddling with the innards of any amp unless you are familiar with the dangers that exist by doing so.

Check your internal circuitry... Maybe there's a misconnection someplace.

hi,

you could start checking the output stage first, then the driver stage, the pre-driver stage, the Vbe multiplier and lastly the input stage.

above recommendation is based on the assumption that you have the schematics of that unit, that you know how to check transistors in-circuit with power on and off state. sounds complicated?

then my best suggestion is bring it to a competent service/repair shop. :? :wink:
