Yamaha CR-1020 Original Owner

Great Receiver - Original Owner

Basics
The 240-volt Yamaha "Natural Sound" CR-1020 offers AM/FM receiving with gauges on tuning, signal and speaker strength. It has a four-gang tuning capacitor with Dolby switch. An OTS internal tuning system can be used manually or automatically.

The receiver can direct recording from several areas in your system---the tuner, a phonograph, a tape deck, an auxiliary device like a CD player and even instruments for live taping.

Specifications
In addition to two jacks for intimate headphone listening with a partner, the 1020 can be fed to three pairs of speakers for more bombastic affairs, able to handle 520 watts of power. FM reception is a noted improvement over the company's earlier models with strong stereo signals. And there's plenty of RF input space on the back (for two tape decks, a CD player, a record player, a television and more). It's not digital, using gauges to indicate strength levels. But it has full audio tuning and signal acquisition capability, from switches for high and low filters to full tone adjustments and loudness control.

Considerations
The Yamaha 1020's internal tuner is highly rated---for its day and today---at 75 watts per channel for 8 ohms, 90 watts for 4 ohms. Its back-lit needle displays make signal acquisition more intuitive, and an FM blend button often helps to clarify a signal after it's been chosen for listening. The 1020 also includes FM muting and full audio muting, useful for some types of recording.
