@alexisvl Could I ask you some advice about HV supplies? I've got a basic Royer type working but seem to be having EMI issues when trying to measure ripple.

i guess i need context here since i'm sharing with newer ppl who don't already know me

i'm building an oscilloscope! from scratch! analog with CRT, modular like a tek 7k. and i'm posting about it because gimme attention plz

it lives here gitlab.com/alexisvl/os2 or here alexisvl.rocks/os2/os2/ but i'm not always great at keeping those up to date

questions always welcome! advice isn't really wanted but won't be met with hostility. just kinda doing my thing over here

alright i'm starting to collect oscilloscope stuff on one of those new-fangled website things

Had to replace the two expensive multipliers, but the circuit has other problems. Even worse than the breadboard, really, though there is no sign the pcb is incorrect.

Which is kind of astonishing, really. Logic would suggest one of the ICs, but I really don't know what its problem is.

Soldered in the first switch. It stopped working. Desoldered it with great effort. Now does not run reliably. So on the pcb it's not behaving any better than the breadboard.

Just now tested my pcb for the Lorenz attractor (based on Paul Horowitz' circuit). youtu.be/22z6oUdtNgg
