It would be hard to find a nicer MX-110 than this unit.
The combination FM Tuner / Preamp has been re-aligned; marginal tubes were replaced; the selenium rectifiers was replaced by silicon; controls have been lubricated; weak caps replaced; and the power supply was tweaked to give the correct voltages.
It is ready to plug in and enjoy.
Note that this model includes a gorgeous walnut Panloc cabinet, the Owner's Manual, and receipts and documents of its service life, including a performance chart.
The serial number is 618Z4.
This is truly a collector's piece. $1200 firm.
