The Marantz 4270 also uses the WC-22 wood case. The wood case makes quite a difference in the final sale price of these units these days. A fully restored, fine condition 4270 with wood case recently sold for $1200.00. Without the wood case and unrestored they will typically sell for $500 to $600 depending upon their condition.

  1. I still own a 4270, and it is still working just fine. I bought the unit new in 1977, and also have 4 Infinity Quantum 1 speakers I use with it. The other components are just a combination of Pioneer(dual cassette deck), a JVC quartz lock turntable, and a Pioneer CD player. I love my system, even though it dosen’t match, but all works together just fine. The newest component (CD player) was bought in the early 90s. If it ain’t broke, don’t fix it, right?
