Here you have a chance to buy F-2842 & F-2843 Sansui boards for amplifier AU919 with restored and cleaned potentiometers and switches.

This is type "A" - Slotted Shaft potentiometer
As you can see on the pictures, potentiometers were dissembled and carefully cleaned, so they are now as new. The same thing I did with switches. Because dissembling of this type of potentiometers is very demanding, a very few peoples do that kind of cleaning.
You will get two boards (F-2842 & F-2843) two potentiometers, switch set and flat cable.
The boards was carefully removed from amplifier and as you can se on the pictures,  they are without damages and burned elements.

Please click on picture to get it bigger, and please look on all pictures.

Installation should be done by qualified technician only, because it is not simple to do that!

I have the same boards which are not restored (because of that,  they have beter price), please look here:
