This would be easier if I had the special machine for installing these tab coil bindings.

I was curious about this 5G LTE filter, so I found a set of min loss pads to measure 75 ohm devices. I haven’t done any work at 75 ohms since I designed CATV amplifiers back in the early 2000s. I don’t have an F type cal kit so I did a response cal (thru).

Hey, it’s 2023, oscilloscope ground leads should not have alligator clips. Here’s my solution. (For situations where a long ground wire is ok.)
I own some fancy DMMs (Keysight 34465A, Keithley DMM6500). Why is it that this old Fluke 45 is the only one in my collection that will measure DC and AC ripple voltage simultaneously without clicking relays? This is a useful feature.
Keyzermas is coming! Santa is hard at work in his workshop, soldering PCBs for Christmas... (Thanks to @chris_gammell for the Midjourney lesson.) Stay tuned for a new episode of The Amp Hour! https://theamphour.com/
Reassembly is progressing very slowly due to some very stubborn case screws that refused to line up with the mainboard standoffs. The mainboard is the large board that sits in the bottom of the case (under the CRT).
The plastic feet use these familiar M3 threaded inserts. All of them broke free upon removal, so I installed new ones. Hopefully they stay in place. I think McMaster stocks a variant with a thicker wall which I’ll try next if these fail. (I really hope they don’t fail, because I don’t ever want to take this instrument completely apart again.)
Someone had removed the tilt feet (the wire loops) for some reason. They can’t be replaced without disassembling the entire instrument. I just added them back.
