Marantz 10B FM Tuner

Audio Proz Inv #: 61510

Excellent condition in our opinion. All original vintage tubes are still in the machine. Excellent FM calibration and service done at Audio Pro, scope alignment for FM is on target. Scope brightness calibration for intensity is max. Scope visibility is very good and easily read but not bright. Basic service of cleaning all controls and switches done. Tube pins and sockets cleaned as necessary. Capacitor and power supply volts all are on spec. It has truly excellent internal cosmetics. It is odd that tubes have only modest use time. All performs well but scope display is weak but again, totally readable. Channel separation better than 40db THD is .2% or less. Unit was heat run for a day. The one problem the unit may have is possibly one of the FM vactrols sometimes is a little off spec by 1 or 2 db or so in level but channel balance is stable over long listening periods for certain. There is a S. S. number scratched into internal chassis top, above Marantz logo almost unnoticeable.
