14、INTRODUCTION This service manual was prepared for use by Authorized Warranty Staions and contains service information for the Marantz Model PM140 Stereo Console Amplifier. Servicing information and voltage data included in this manual are intended for use by knowledgeable and ex- perienced personnel

15、 only. All instructions should be read carefully. No attempt should be made to proceed without a good understanding of circuitry operation. The parts fist furnishes complete ordering information. Most replacement parts should be ordered from the Marantz Company. However, a simple description is in-

16、cluded for parts which can be obtained locally. 1. P.W. BOARDS As can be seen from the circuit diagram the chassis of Mode! PM140 consists of the following units.
