Cambridge Audio Azur 840a v2

The unit is in near mint cosmetic condition but it is not functional. I powers up fine, but has the typical issue in these units where volume control does not respond to the knob. The Internet forums identify this as the encoder behind the knob either being dirty or worn out with instructions for cleaning or replacement. I have no electronics experience so I used it like this fine with the remote. Unfortunately, the remote just stop working. I am hoping somebody might want to fix. This was the top of the line integrated amplifier for Cambridge Audio (originally over $1800), a true audiophile amp that I have enjoyed enormously and I am sad I can no longer use, the unit is very similar to the current model Azur 851A, with very minor refinements. You can find excellent reviews of this exceptional amp easily in the internet.everything on the photos is included: unit, remote control, power cord, RCA cable, coaxial cable for interconnecting other Cambridge Audio units (CD, amp, etc.), original manual. I will be packed with a lot of protection to ensure safe delivery.
