An excellent power amplifier from McIntosh from the personal collection of the MC2505 is on sale. Switched to 234 volts +-10% normally (i.e., according to the specification, the permissible supply voltage is from 210 to 257 volts), the plug has been replaced with a European one. It is positioned as a NI-END class device. The MC2505 is a 1967 model, was produced for about 11 years, about 11 thousand copies were produced. A real vintage.
