Tek p5205 HV differential probe teardown. BTW, what are the red and brown wires?
Olexandr:
I want to repeat the scheme of this device for my own use, but the scheme lacks the denominations of almost all capacitors, based on this I want to ask everyone who has such a device to help me, you need to measure and indicate which capacitors are there. :-DMM

Just in case somebody needs it: here are some nice pictures of the P5205 PCB's top and bottom sides.

A year ago or so, I got a pair of P5205 HV probes fairly cheap, without noticing the TekProbe supply needed. Yikes!
I did not want to cannibalize the probes - being inspired by @128er, I made my own.
Hacktronix
- simple ±12V
- no ±5V nor offset rubbish
- some 3D print parts
- mains filter waiting in the parts drawer
- contact plate made with Dremel, drill press and carpet knife, out of a salvaged PCB with huge ground planes
- mains xfmr salvaged out of a phone system
- housing made from a salvaged MEADE battery charger
- ...
If someone needs the shroud, I can share collada or stl files.
Thanks for all the information shared in this thread!
Attached you find some pics.

Please put the shroud .stl here:

Would help me much with a TekProbe breakout box!

if BNC cable from that PSU output to scope is long, you risk reduced signal integrity (reflection), if its me, i will make an adapter from tek BNC input directly to normal scope's BNC output with power pins socket on the side, so PSU is external device with wires connecting to the adapter (which will be connected directly to the scope) much like tek 1141a diff probe with external 1142a psu module.
