Quick service response. A useful and very rare service manual with all details. I recomend this service.

I ordered this manual sometime in the afternoon and I received it on my e-mail the same evening.
This is a fantastically good and properly scanned copy of the original manual. All pages are of the same scale and they overlap each other. It means that you can print the manual and easily make it as a convenient paper manual.
The content of the manual is fantastic. Alignment descriptions, PCB layouts and elementary diagrams are explicit and precise. I immediately found what I was looking for. Thanks to this manual and Owner-Manuals.com my amplifier is alive again. Many thanx indded!
;
The manual was well-scanned and easy to read. As an added bonus, the Operator's Manual was bundled with the Service Manual!
I'd definitely use owner-manuals.com again.

(E-2) : Crosshatch (50Hz) (E-5) : Monoscope (50Hz) Adjust the overscan to 8.5 ± 0.5% (Monoscope) (E-5) V-LINEARITY 50 Adjust the linearity to the best. (E-2) V-S CORR~ Already preset (**). (Adjust this unless the linearity is achieved.) (E-2) V-CENT50 Align the center of the screen to the geometric center of CRT. (E-5) H-CENT50 Align the center of the screen to the geometric center of CRT. (E-5) H-SIZE50 Adjust the overscan to 8.5 ± 0.5% (E-5) E/W PARABOLA50 Adjust the end of the line of the crosshatch to be (SIDE-PIN) straight. (E-2) EW-CORNER50 Adjust the end of the line of the crosshatch to be (SUB-SIDEPIN) straight. (E-2) TRAPEZIUM (50) Already preset. (Adjust if the quality is specially poor.) (E-2) OTHER On the items of V-AMPLITUDE60, V-LINEARITY60, V-S CORRECTION60, V-PHASE60, H-PHASE60, H-SIZE60, E/WPARABOLA60, E/W-PARABOLA60 and TRAPEZIUM (60), the compensation data is automatically input if the 50Hz mode adjustment is done.

SUBBRIGHTNESS ADJUSMENT (I2C BUS CONTROL) (RF SIGNAL)
1. Receive the window pattern signal with AV input. 2. Make the image normal with the remote controller. 3. Select the sub-bright adjustment mode with the remote controller, and adjust the right dark white area of the window pattern to 2.7 ± 0.3cd.
* Receive the crosshatch pattern signal or equivalent signal. 1. Make the image normal with the remote controller. 2. Adjust the 3rd (1 thru 5 from the left) black of the window pattern to sink. 2 FOCUS ADJUSTMENT 1. Receive the Monoscope pattern signal. 2. With the remote controller, make the image normal. 3. Adjust the focus VR to make the vertical line of "5" in "E-5" display upper left part of screen as fine as possible.
However, if it is largely deviated when it is checked in the 60Hz mode, readjust it in the 60Hz mode.
