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.

2 Actual Vofs adjustment (1)
A
(From 1 )
(Check Vofs_max1 with the red 760 signal.) Perform aging with RST MASK 01 (white) displayed for 3 seconds: MKS S51
Set to RST MASK 17 (pale purple).
MKS S67
Set VOL OFFSET to 024 (15 [V] ).
B
VOF 024
Are there any dark cells? Yes Gradually increase Vofs data VOF ��� until dark cells disappear (Vofs should be 255 (60 [V]) or less).
No
Set Vofs_min1 to 024 (15 [V]).
Note: This setting value becomes the value for Vofs_min1.
Vofs_min1
[STEP]
Note: Take note of the value for Vofs_min1.
Is Vofs_min1 144 (38 [V]) or smaller?
C
No
Replace the panel again or abnormality in circuits
Yes
Return the Vofs value to the tentative voltage setting.
