My TEKTRONIX 5403/D41 oscilloscope is died. The fault is likely in the low-voltage power supply section, but unfortunately I have not the manual, so that I cannot repair it... Can anybody help me..? A simple *.jpg scan of the supply-schematic may be enough to start.
Many thanks in any case to all those will read and take into consideration my message.
