very good manual, with detail and clarity in esquematic diagrams and waveforms .

Very quality copy of original service manual, which contains the circuit diagrams, PCB and lists of components, well as recommendation for calibration procedures of device, also everything else, that need for repair, tuning and use this oscilloscope.
All presented copies have high-resolution, so you can view all in detail.
This manual will very useful for simple owners and for repairers.
I recommend these manual, because myself is owner of Philips PM3216 and I need sometimes servicing these oscilloscope (principally calibrating).
Also, these document is an example of excellent design of technical documentation.
ADJUSTMENT
Equipments required
Oscilloscope Frequency counter Test tapes, MTT-111N (0004 5032) and MTT-113N (0004 5033) Two 8-ohm resistors
Pre-adjustment procedure
1. Clean the head and all tape handling surfaces using standard cleaner and cotton swabs. 2. Connect an 8-ohm dummy load to headphone jack of each channel. 3. Set the main volume to the maximum. 4. Set the tape speed volume to the center position.
Head azimuth adjustment
Never use a magnetized screwdriver for this adjustment. The head azimuth adjustment screw is located just under the notch which can be seen when opening the cassette door. 1. Connect a oscilloscope to the dummy loads. 2. Set a tape MTT-113N holding the door open, and playback the tape. 3. By turning the adjustment screw slowly, adjust for amplitude of both channels at maximum and adjust for the waveforms in the same phase reading on the oscilloscope.
