This is the Marantz 2220B. It was at the lower end of the Marantz offerings but still offered great quality manufacturing and sound. It’s rated at 20 watts per channel into 8 ohms.
These little receivers are great for someone just getting into vintage audio. They can be purchased for a reasonable amount and, once serviced, will last for years.
Nothing too complicated inside which makes them easier to work on. The 2220B’s sell from around $450.00 for an average condition un-serviced unit all the way up to $1000.00 for a clean and restored unit.
