So I got this so I could safely use my oscilloscope with HV, but I'm confused

How can I measure up to 3kv differential if the max voltage vs ground is 1kv for each of the probes?

I want to be able to use this to work on electrostatic CRT deflection amps and so forth where I can easily reach the 3kv. Can I really use this or do I need to return it?

Am I doing this right?

First time building something with turret boards. Just wanted to make sure I'm not doing something stupid.

Don't worry about the wires looking too thin. They are double insulated with kapton and ptfe so are good to over 600V.

ADHD Engineering GU-17 amp

Finally built this prototype after thinking about it for ages.

Schematic is on my computer and I'm posting this from my phone so can't post it just now.

Its just a basic 12AX7 LTP phase splitter and a GU-17 as the power tube.

Now that I've got the prototype working I've ordered some turret boards and such to build it proper and build 2 of them so ive got stereo.

The power supply is kinda janky. The comverter I'm using for 250v likes to be noisy and I had to filter it more than I had liked.

It was fun finally building this thing. Next I'm going to see how well it works when I add some feedback.

ADHD Engineering: differential amplifier

Built this a few years back. No schematic, don't remember why I did it.

Its supposed to be a differential amplifier based on how it's wired.

Anyone else start projects and then find them years later and not remember why they did what they did?

This isn't even finished. Its missing wires connected to power and output lol.
