Buying notes
Marantz tube monoblock power amplifier from 1960-1962. One of the most collected tube amplifiers ever made. Always sold in pairs. Output transformer condition is critical and very expensive to remedy. Check the tube complement; original tubes add value. Service by a tube specialist is essential on any example at this age.
