MAC 1500 STEREO RECEIVER
INTRODUCTION
All Mclntosh tuners are carefully aligned and tested at the factory using the finest
available test equipment. All Mclntosh tuners will meet their published specifica-
tions when shipped from the factory.
After extensive operation, especially when tubes have been replaced, it may be
desirable to realign the timer circuits for best performance. This manual gives
complete information on the circuit realignment procedure for the MAC 1500
receiver.
The test equipment listed below (or its equivalent) is necessary to properly
align a MAC 1500. The accuracy of the alignment will be directly related to the
accuracy and calibration of the test equipment used.
FM Signal Generator (Measurements 210A or equivalent)
VTVM
Multiplex Generator (RCA WR51A or equivalent)
10.7 MC Generator (Preferably crystal controlled)
Oscilloscope (Hewlett -Packard 120B or equivalent)
Harmonic Distortion Analyzer (Hewlett-Packard 330B or equivalent)
If the necessary test equipment is not available, alignment should not be
attempted. You may contact the Mclntosh Customer Service Department for
additional information.
