Top quality manual. Covers all aspects you'd expect in a top quality service manual for this Panasonic VHS VCR. The manual resolution is high. Another top quality manual from the only site worth downloading manuals from! If you're looking for a manual for the PV-9662 VHS VCR, this is the one you'll want to get!
;
complete part-lists and pcb layout, schematic diagram is good enlargable,
;
Excellent, fast delivery, excellent product. Good luck!

This manual is for the usa model only. But it is clear
, accurate and comprehensive, including board layouts and schematics.
I found it extremely useful for my mitsubishi dp-86da, but the same diagram would also work for the realistic lab5000 and hi fi 80. Thanks.

Great to have extra resources for Service Manuals, Now days you can really not trouble shoot efficiently without one , Wayne at IRIONS TV & ELECTRONICS REPAIR Clearwater , Fl. 33755 727-446-7955
9. DC Balance / Mono Distortion Adjustment Settings : � Test point : TP3, TP4 (DC Balance) : TP5(Lch), TP6(Rch) (Distortion) � Adjustment location : L801 � Input level : 60dBµV Method : Set to FM 98.0MHz and adjust L801 so that the voltage between TP3 and TP4 is 0V ± 300mV with minimum distortion.
15. REC/PB Sensitivity Check (DECK 2) Settings : � Test tape : TTA�602 � Test point : TP7(Lch), TP8(Rch) � Input signal : 1kHz (LINE IN) Method : Apply a 1kHz signal and REC mode. Then adjust OSC attenuator so that the output level at TP7, TP8 becomes 280mV. Record and play back the 1kHz signals and check that the output is �1dB ± 3.0dB.

10. Tape Speed Adjustment (DECK 2) Settings : � Test tape : TTA�100 � Test point : TP7(Lch), TP8(Rch) � Adjustment location : SFR1 Method : Play back the test tape and adjust SFR1 so that the frequency counter reads 3000Hz ± 5Hz (FWD) and ± 45Hz (REV) with respect to forward speed. 11. Head Azimuth Adjustment (DECK 1, DECK 2) Settings : � Test tape : TTA�300 � Test point : TP7(Lch), TP8(Rch) � Adjustment location : Head azimuth adjustment screw Method : Play back (FWD) the 10kHz signal of the test tape and adjust screw so that the output becomes maximum. Next, perform on REV PLAY mode. 12. PB Frequency Response Check (DECK 1, DECK 2) Settings : � Test tape : TTA�300 � Test point :TP7(Lch), TP8(Rch) Method : Play back the 315Hz and 10kHz signals of the test tape and check that the output ratio of the 10kHz signal with respect to that of the 315Hz signal is 0dB ± 3dB. 13. PB Sensitivity Check (DECK 1, DECK 2) Settings : � Test tape : TTA�200 � Test point : TP7(Lch), TP8(Rch) Method : Play back the test tape and check that the output level of the test point is 280mV ± 3dB. 14. REC/PB Frequency Response Adjustment (DECK 2) Settings : � Test tape : TTA�602 � Test point : TP7(Lch), TP8(Rch) � Input signal : 1kHz / 10kHz (LINE IN) � Adjustment location : SFR351 (Lch) SFR352 (Rch) Method : Apply a 1kHz signal and REC mode. Then adjust OSC attenuator so that the output level at the TP7, TP8 becomes 28mV. Record and play back the 1kHz and 10kHz signals and adjust SFRs so that the output of the 10kHz signals becomes 0dB ± 1.0dB with respect to that of the 1kHz signal.
