I only buy tools from Germany, Japan, USA and Taiwan (ROC), (in no particular order). I have Snap-On tools that are in excess of 50 years old and still being used daily. Tools from China, India and

I found a seller that combines shipping, so the total for three ceramic drivers was $5.10 https://www.aliexpress.com/item/4000440746585.html

I'm lucky in this regard that I live in Japan, so obtaining Japanese tools is somewhat unavoidable. :) Even when I was living in Australia, I would seek out Japanese and German tools. When working on

I like my trimming screwdrivers as stubby as possible, because of their small rotational elasticity. It helps overcome the trimmer's friction, providing higher precision control. A ceramic stem works

Jared, Thanks for the pics. I suspect at some point I'll pick up a modern DSO that can handle frequencies above 500MHz, just so I can capture such signals. The "signal" that was causing me concern

Jared, I was able to find these two brands on AMAZON. Vessel makes a great set of JIS Screwdrivers as well, invaluable when working on Japanese equipment. I also found some very high quality, German

Mike, Great advice that needs to be repeated. "Troubleshooting Your Oscilloscope: Getting Down to Basics" is a cornerstone of the repair process. I was fortunate to find this early on, when

Both Vessel and Engineer brands are very good Japanese brands I have a bunch of tools from both brands. You can find them everywhere here in Japan, not sure about other countries though.. For

Hello, The TekScopes articles mentioned earlier are a great place to start. If you lost track of them or cannot find them, contact me at <mmerigATsilverstarDOTcom> and I will send you pdf's. If I

Or Vessel ceramic screwdrivers from Japan.? I used them in the early 2000's to adjust inductors in an oscillator.? Way easier than using a regular metal screwdriver; the oscillator drifted off

Dave, I bought a set of ceramic screwdrivers about a year ago, from Amazon. The best thing I can say about them is that they were inexpensive. They are also very cheap. They do, however, get the job

The schematic depiction of switches in Tek schematics isn't always clear to me. Yes, I was clear on the 5, 2, and 1 ns circuits - really the 5ns and 1/2ns circuits, and that K450 switches between

Of course, all signals have a common frequency source (variable timing out is a special case). Raymond

I'm not sure if you realize that 2ns and 1ns aren't generated by the 5ns+ circuits; they are separated by K450-S1, which selects either all 5ns+ signals or both the 1ns and 2ns signals. The fact that

Well, surprise, surprise.? I actually looked at the plugin and I was definitely wrong on the trigger output. Trigger output valid from 0.1 us to 5 sec. In mine, you get a + spike at the appropriate

Nope, not intended nor expected. But I don't expect to see the MARKER OUT output to be putting out anything while in 1ns mode. The 1ns output on the 1ns ONLY BNC is otherwise fine - as good as my
