Huawei RRU disassembly

Hello everybody!
Has somebody experience in disassembing Huawei RRUs?
I will be able to get the scratchy old RRUs, i want to get a RF amplifier boards - is it possible to disassemble a built-in duplexer?
Best Regards
Nik0

I also want to get acquainted with such specialists,
but unfortunately, such people are just dinosaurs in this world ))

from a business point of view, only need only low-paid engineers,
like robots with manual from the R&D department ))

here are some of my photos, just for relax ))

...I had a lot more devices, but it's very difficult to make good photos, and I solve problems with the firmware.
just answered that you would know that we are alone here ))
