TEKTRONIX 5403 OSCILLOSCOPE: help for power supply schematic

[gianni miglio]

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.

I can send you a PDF version of the 5403 manual as an email attachment
if you can receive a 7.05 MB attachment. Let me know if you would like
this file and the email address to send it to.

Download from here and this will help:

Check for dry/leaky/dead-short electrolytics in your 5403's LV supply.
Most often, the big "silver can type" electrolytics dry out.
