It becomes interesting when you want to replace the input filter in a 1982 Solartron 7081 8 digit voltmeter - because it also contains a fuse and a rather complex voltage selector.

Fortunately Schaffner still make the same type (+1 Schaffner!), so the only pain is that it cost about half the price of the voltmeter :)

Yeah, that's where it becomes worth the arseache to disassemble the damn thing and repair it, I'd think.

With all due respect to the 7081, I am quite thankful to be able to cling to THIS side of the voltnuttery line.  :phew:

But it is SUCH a slippery slope...  :-DD

The real pain with the 7081 is that it didn't have input connector and lead. Hence

As for my drive, it is quite steep enough (~10%) that algae is a sufficient grease :(

Hmm algae and grease, you might as well give up then cos you're  a voltnut. 😂

When I see connectors and inlet provision like that Solartron, they get IEC-ized instantly!

....

Not really TEA but I have been suitably impressed today. Playing with some PIC10F320 microcontrollers. I think it is bloody amazing that you can get a whole damn computer in a SOT-23 package now. Literally all I'm using it for is generating two digital signals 180 degrees out of phase to drive inverter MOSFETs and enable/disable itself based on an ADC sample. This does however replace an entire 74hc14, regulator, a 2n3904, a trimmer and some external passives that were doing the job before with just itself, a tant and a much smaller regulator. Impressed :-+

It's bloody tiny. That's a DIP / SOIC footprint board.



And yes I did lose the first one on the floor  :-DD

Never mind the hoover will announce that it's found it when you do the hoovering, shame it'll bugger it as well though 🤣
