Im still struggling with this power supply If I remove the A5 board from the scope the power supply voltages return to normal and can be adjusted to spec by adjusting R938. As soon as I plug the A5

All channels equally impacted. Yes I was referring to the big National Semi IC. Sweep rates of 400us and slower are just fine. Anything faster is a total mess. I see the MPC860 now - right next to the

Thanks Hakan! That's super helpful. Unfortunately while there are reference designators for the components in the detector head, they do not appear on the parts list. This is still way more

I had some pictures that I took when doing this on my TDS784A but notes were nowhere to found. So I opened up the 784A and together with the pictures I composed a document on how it's done. Could be

All the Chinese probes and acess are junk. Strongly suggest to check the TEK manual for each probe, find the TEK part number and search eapy. There are GENUINE TEK slip on tips available for each

That has been discussed to death, but to recap: The 647 was tek's first wide temperature range scope. It operated from -30 to +65C, which would melt the beeswax out of the transformers. Tek did two
