Funny, the power summary given by schematic values (5.2 V/6 A, -8.6 V/7 A, 8.6 V/3 A and 100 V/ 1 A is way above the 40 W number in the rear panel. More news next week!
No.
1A,2A,3A,6A,7A
they are "address" where these lines are going.
Also in first post you tell that it "chirp" when it try start.
Mostly but of course not exactly allways it means that primary try start. In start up phase it go to "error" and stop. After short time it may "chirp" agen becouse it agen try start.
I have repaired several of these where have been this "cirp" without power up, and really (in my case) all was secondary problems and electrolytics and/or some of diodes in secondary.
(yes I have also seen broken T948 winding just near solder point. but it was different case)
Of course problem may be in many places in individual unit but I still recommend you check these secondary outputs becouse it really is common known problem in these.
Look diodes CR954 - 957, CR960-963, CR967 and
979 970.
Then test every electrolytics after these diodes, there are exatly 8 of these.
They may be "open" or "short" or normal. If someonme tell they do not go to short. I can proof they can. Also diodes may fail to "open" or "short". Measure them. Pic up other end of diode and measure. If you find failed diode (short or open) specially then look this circuit electrolytics.
As someone tell. I recommend change all these secondary output electrolytics, if fail or looks ok. They are not good and they are old. (and depending where it is manufactured, and what lot, there may be moderate good capacitors or not so good.)
-------------- more about what are these 7A and 3A etc.
Yoy can see in pictures example this (if you look sheet 7 and there 8.6V power output.):
+8.6V
TO
3A
8 (around this 8 is small box)
look sheet 8, it is going there. (power distribution "map"
Then find location 3A there (in sheet
This address system is good very common and now you easy find where they go.
(exept that in my service manual there is small error and destination is in location area 4A, so it need also be wakeup when use these manuals, there are also small errors what make some times things more fun.
