This is a classic solid state Marantz 2245 receiver. It was produced from 1971 to around 1976 and put out 45 watts per channel into 8 ohms. The retail price in 1971 was around $450.
It has the typical look a a mid 1970’s Marantz receiver with the brushed aluminum face plate, blue tuning dial and flywheel tuner, which they called Gyro Touch Tuning.
As you can see the Marantz 2245 has a Mid tone adjustment which is nice. It also has a Low and Hi Filter along with Loudness and Muting.
It really looks great in the WC-22 wood case but keep in mind that the wood case can inhibit the flow of air into the unit somewhat which can result in overheating. Still, they do look good in wood! The color of the tuning dial is usually off quite a bit from the original color because the vellum paper that is used yellows over time giving the blue more of a greenish color. Many people change ou the original lamps with LED lamps. They are nice but sometimes are a little more pronounced than the original lamps.
Most of the Marantz receivers of this time are well built. Restorations aren’t that difficult either as it is nicely laid out and many of the boards will swivel out of place without completely removing them. For a look at a 2245 restoration check out at RetroVoltage.
One thing you will run into with vintage Marantz receivers, and all vintage receivers for that matter, is that the switches and potentiometers will become dirty over the years. This can result in some strange behaviors. So, before spending hundreds of dollars on a restoration try cleaning the push button switches and pots on the receiver.

Mid 1970’s Marantz receivers are very popular and the Maratnz 2245 is no exception. Fortunately they sold quite of few of them so they aren’t particularly difficult to find. But, demand does keep the prices up. The 2245 is a good mid range receiver and has a reputation for producing a great sound. Prices have climbed over the last few years and will probably continue to do so.
