Hi All!

I have an old 2235 'scope which has died on me.
It looks like the resistor R909 and Q908 are fried . It also looks like
the IRF820 ( on heatsink) is blown.
Can anyone help with an excerpt from a service manual ( diag) or part
numbers/values ?

Does this happen often with these babies ?

Regards

John
