muy buen manual por lo completo de este algunos esquemas estan muy divididos lo que hace algo dificil el seguimiento.
;
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.

1. Tape Speed Adjustment Settings : � Test tape : TTA � 100 (Tape center) � Test point : Phones Jack (J101) � Adjustment location : SFR301 � Dolby : OFF � MSP : CLASSIC � DSL : OFF � Tape selector : NORMAL(AUTO) � Volume : MAX Method : Play back (FWD) the test tape and adjust SFR301 so that the frequency becomes 3015Hz ± 10Hz. Then confirm WOW is less than 0.50%.
