Sansui b3000 schematics

This item is not a repairable item. It is a throw away item
There is a working one for sale on fleabay for R200. That is about £10 GBP.
There are no service manuals or even schematics because when they failed under warranty, they were replaced.

There are parts schematics in the link.

Similar model G-E750 link has a schematic. Please click Helpful or Not Helpful to respond to this suggestion.

Yes in order to have audio going to your spare speakers from the sub .You would need to use the hi level inputs comming from the reciever outputs connected to these hi level inputs..The sub will then crossover the audio to their proper outputs..Hope this helps you

Mine was manufactured in 1990-91, & I have the owners manual! IF you're still looking, for $10 time/expense I'll go copy & mail, IF you're to contact me through here & send verifiable postal money order up front. [email protected]. {FYI- I also have manuals for other components it came with}.

i have a sx700 sansui receiver, that the receiver is working fine.
My problem is on the amplifier section
Do you have a schematic diagram ?
Beeing an old amateur radio technician, that is, working with sophisticated receivers don´t see any problem to help you.
It is my oopinion however that unless I can have a copy of the complete schematic diagram it will be impossibleto start giving you ideas
Can you provide me a coopy of the schematic diagram
And tell me if the amplifier section is working fine and also (very important) if other frequencies, excluding fm are working.
Thank you inadvance,

I think you're on the right track. It sounds like the problem is in the horizontal deflection circuit or pincushion circuit.Maybe a bad solder connection or a resistor burned loose from the circuit board. Stargazer
