The Marantz 2285B Stereo Receiver is the highest-end, highest-power model in the 22xx range with exceptional build and sound quality. Marantz has simpler model numbers that don't provide a lot of detail. Price is fixed, cash on collection from my location in Crouch End, or paypal and after receiving in my account the money i fast send the item.
Some of the pots required cleaning otherwise, everything still works fine after all these years. Are you sure it's not a Marantz SR-4000 I own one of these.
