Gaining access to Tek 5403 power supply board?

Brad Thompson <brad.thompson@...>
 

Hello--

Before I attempt anything really stupid (*) <g>, can anyone point me to instructions
for gaining access to the power supply board in a Tek5403 scope?

Also, does a power-supply schematic exist for this scope? DC and ripple voltages are
out of spec for all supplies except the -30 V supply.

Thanks in advance, and 73--

remove the support bar that partially blocks access
to a couple of filter capacitors' terminals....
