Hello Compacters :-),
Finally, I bought the Classic. Good thing is that the picture tube is fine
(I can get a raster increasing internal sub-contrast control). But there is
no Mac display, just the raster.
I have found a burned component in the tube neck circuit; it is marked as
RC3 and seems to be a resistor in one of the grid circuits. Neck circuit
(PCB) is marked as 630-0528
I wonder if somebody has the Classic schematics (mainly for the display and
power supply part). If so, I would be very interested in getting a copy.
Also, any hint about what can be wrong will be welcomed.
By the way, Mac starts with the 'bong' and then there is HD activity for
some minutes, so I think it is booting just fine.
Thanks for your help!
Best regards,
JOSE
