Probably it never existed a 1081 official service manual from Commodore, it's look more like a NAPCEC service manual & diagrams compilation of the 1084 series and his variants, like the nap6523, 8cm505, 1084S, 1084P and obviously the 1081. It's more complete than other scans and the quality of the scans also are far superior. It has two circuit diagrams variants of the 1081, mono and stereo versions. It doesn't include a diagram for the Philips CM8500 or CM8501, they look like the 1081 but they are slightly different.

Rapid, clear well done as all the scheme I downloaded from this site. Great job very functional and very useful
;
Great copy of the manual, has all information required for servicing,

I work at an authorized service center and I can tell if a manual is as it should be. This one is. It may be a scan, but a very good one at that. The interesting part for me was the curcuit diagram which was scanned at high quality, making it as good as the original. I will definitely be back as a customer. I need not say this, but I will: the price was the best. Thank you owner-manuals.com .

really a very good manual even sometimes the quality is no so good as before still very readible and very very useful!
ADJUSTMENT <DECK> (FX-NH2000)
< DECK SECTION >
1. Tape Normal Speed Adjustment Settings : � Test tape : TTA�100 (Tape center) � Test point : TP1 (Rch), TP2 (Lch) � Adjustment location : SFR1 Method : Play back the test tape and adjust SFR1 so that the test point becomes 3000Hz ± 5Hz(FWD) Then check REV speed is 3000Hz ± 45Hz. 2. High Speed Check Settings : � Test tape : TTA�100 (Tape center) � Test point : TP1 (Rch), TP2 (Lch) Method : After normal speed adjustment, play back (High speed) the test tape. Then check tape speed is 6000Hz ±400Hz (FWD). 3. Head Azimuth Adjustment Settings : � Test tape : TTA�300 � Test point : TP1(Rch), TP2 (Lch) � Adjustment location : Head azimuth adjustment screw Method : Play back the 10kHz signal of the test tape and adjust screw so that the output becomes maximum.Next, perform on each FWD PLAY and REV PLAY mode. 4 PB Sensitivity Adjustment (DECK1, DECK2) Settings : � Test tape : TTA�200 � Test point : TP1 (Rch), TP2 (Lch) � Adjustment location : SFR301 (DECK1, Lch) SFR302 (DECK1, Rch) SFR303 (DECK2, Lch) SFR304 (DECK2, Rch) Method : Play back the test tape and adjust SFRs so that the output level of the test point becomes 245mV (DECK2), 260mV (DECK1). 6. REC/PB Sensitivity Adjustment (DECK2) Settings : � Test tape : TTA�602 (NORMAL) � Test point : TP1 (Rch), TP2 (Lch) � Input signal : 1kHz (LINE IN) � Adjustment location : SFR305 (Lch) SFR306 (Rch) Method : Apply a 1kHz signal and REC mode. Then adjust OSC attenuator so that the output level at the TP1, TP2 becomes 0dB (17mV). Record and play back the 1kHz signals and adjust SFRs so that the output is 0dB ± 0.5dB. 7. REC/PB Frequency Response Adjustment (DECK2) Settings : � Test tape : TTA�602 (NORMAL) � Test point : TP2 (Lch), TP1 (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 TP1, TP2 becomes 0dB (17mV). Record and play back the 1kHz and 10kHz signals and adjust SFRs so that the output level of the 10kHz signals becomes 0dB ± 0.5dB with respect to that of the 1kHz signal. 8. REC/PB Frequency Response Check (DECK2) Settings : � Test tape : TTA�615 (CrO2) � Test point : TP2 (Lch), TP1 (Rch) � Input signal : 1kHz Method : Apply a 1kHz signal and REC mode. Then adjust OSC attenuator so that the output level at the TP1, TP2 becomes 0dB (17mV). Record and play back the 1kHz signal and check that the output is 0dB ± 2.0dB. 9. REC/PB Sensitivity Check (DECK2) Settings : � Test tape : TTA�615 (CrO2) � Test point : TP2 (Lch), TP1 (Rch) � Input signal : 1kHz (LINE OUT) Method : Apply a 1kHz signal and REC mode. Then adjust OSC attenuator so that the output level at the TP1, TP2 becomes 170mV. Record and play back the 1kHz signal and check that the output is 0dB ± 2.0dB.
5. PB Frequency Response Check (DECK1, DECK2) Settings : � Test tape : TTA�300 � Test point : TP1 (Rch), TP2 (Lch) 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 . Next, check that the Lch and Rch difference level of 10kHz signal is less than 2dB.
