Opis: 10MHz dual trace oscilloscope
                                    The Advance OS250 Oscilloscope is a 10 MHz dual trace
instrument with a 10cm x 8cm display. It is designed
for use in general purpose laboratory work, educational
uses, TV and servicing applications.

It features two identical input channels with a maximum
sensitivity of 5mV/cm and a bandwidth of DC to 10MHz.
The two channels may be viewed separately, alternately
at fast timebase speeds, or chopped at a 250kHz rate at
low timebase speeds.

Particular attention has been paid to trigger performance,
and the system used includes a variable control with
bright line operation in the absence of a signal,
or when the trigger level is outside the range of
the input signal.

My oscilloscope

This is my only oscilloscope, and im depending on him to do my school project. He always have been a got buddy, but now need some service.. and this manual are a great help!
So far im i see that the Diode bridge (MR301) are not rectifying well.. he are producing a AC current on output, and the DC tension is about 30V (instead 155V, even if i adjust R320). But after i replace a Diode Bridge by a new "2W08", after a couples os seconds i have a drop of tension across C315 (155V to 60V).. i need to troubleshoot a little more, but maybe is the C315, TR301 or TR302 that are not healthy.. we will see :)

have a good day everyone! and thanks again!
