The Marantz 2325 came out around 1974 with a list price of $799.95. It was discontinued some time around 1976. It produced 125 watts per channel into 8 ohms. This particular unit has the WC-43 walnut case. I believe the WC-123 case also fit this model. The 2325 weighs just under 50 pounds. It was Marantz’s flagship receiver at the time.
The 2325 had built in Dolby Noise Reduction and well as fantastic damping for tight bass.
If you’re looking to rebuild your Marantz 2325 there is a good reference site called Rebuild Your Marantz. Very detailed with lots of photos etc.
The 2325’s can sell from over $500 for a non-working parts unit to over $1400 for a fully restored unit.
