Old Philips PM 3217 scope went dead.

Hello,

My trusty Philips oscilloscope finally kicked the bucket. This morning I turned it on, it made a short buzz sound and then went completely dead. I didn't notice any smoke or odor.
It worked fine before.

Would be this typical to cap failure in the PSU?

Personally, I don't think it will be worth my while going further than replacing electrolytic caps. So it's either that or selling it on ebay as spare parts.  I do love these analog scopes though.

Why wouldn't you want to fix it? It could be as simple as a dead  diode. NOT CAPS!!!!

Measure the voltages in the power supply to start with. It could be something simple...

I have a similar era Philips scope that died and it was the electrolytics (not saying yours has an identical fault). Found that after fixing up the power supply other things started to fail, symptomatic of electros in other parts of the unit drifting out of spec. Bought a DSO POS to get me through until I located a decent old Tek.
