I needed a service manual as the display on my oscilloscope was very dim. I thought I'd give owner-manuals.com a try, as they advertised a huge number of manuals. Sure enough they had one listed. I bought it hoping it would be useful... actually, I bought it hoping it would be readable! I've had manuals from online sources in the past, and been very disappointed. Not this time! An excellent manual, complete, and very readable. Using it I fixed my 'scope, and as such the manual was an investment that paid off manyfold. Do I have any complaints? One very minor one - The circuit diagrams could have been scanned at a higher resolution, as some of the details were a little difficult to make out - not impossible, just not as easy as my old eyes would like! Overall, I'm very satisfied with my manual, and I will certainly be using this company again. Well done.

I Have looked for this manual for quiet a while now, I have finally found it here. I believe this is the only place they have them in a very nice scan, pages are very clear to read, some of the pages are a bit tilted but overall it is great to have this manual available for purchase. Thanks

Quick delivery, the document was usefull, although the copy was i little bit unclear in the details.
5. DC BALANCE CHECK (FM) Requirement Measuring equipment: Digital multi-meter Test point: TP2, 3 (1) Adjust the reception frequency of the main unit to 98.0MHz. (2) Check that the test point voltage difference between TP2 and TP3 is 0mV±500mV.

Standerd Signal Generaor
SET TP Lch Rch GND
Connect to the respective measuring equipment
6. IF ADJUSTMENT (MW) Requirement Measuring equipment: Oscilloscope or Millivoltmeter Test point: TP8(Lch), TP9(Rch), GND Adjustment point: L802 (1) Adjust the setting of Standard Signal Generator (hereinafter S.S.G.) to 999kHz of 30% variation. (2) Adjust the receiving frequency of the main unit at 999kHz. (3) While looking at the waveform on the oscilloscope, reduce the output level all the way (till a certain degree of is monitored through the oscilloscope). (4) Adjust L802 until the waveform of the oscilloscope reaches the maximum. 7. TRACKING ADJUSTMENT (MW) Requirement Measuring equipment: Millivoltmeter Test point: TP8(Lch), TP9(Rch), GND Adjustment point: L952, L953 (1) Adjust the S.S.G. setting to 999kHz of 30% variation and reduce the output level all the way (till a certain degree of is monitored through the oscilloscope). (2) Adjust the reception frequency of the main unit to 999kHz. (3) Adjust L952 until the value of the millivoltmeter reaches the maximum. (4) Adjust the S.S.G. setting to 603kHz of 30% variation and reduce the output level all the way (till a certain degree of is monitored through the oscilloscope). (5) Adjust the reception frequency of the main unit to 603kHz. (6) Adjust L953 until the value of the milivoltmeter reaches the maximum. (7) Repeat the adjustment 2 or 3 times from step 1 to 6 above.
