About this model
McIntosh's own legacy list dates the MA230 to 1963–1966 and rates it at 30 watts per channel. It is a hybrid of a kind: dealer descriptions mention a solid-state preamplifier section feeding a tube power stage, with four 7591 output tubes plus 12AU7 and 12AX7 tubes. This example still had all its original McIntosh 7591s, Sylvania 12AU7s and Amperex 12AX7s, and came with a refinished wooden case and its lower tray.
The 7591 was a popular American output tube of the early 1960s; the archive's EICO ST-40 uses four as well. Original McIntosh-branded tubes add real value to an MA230, so keep them even if you listen through replacements.
