TU-8500 help

[Cali420]

Hi everyone, I just came across this community doing research on a pre-amp I found for sale on eBay while looking for a new phono pre-amp.

This is the pre in question

Elekit Vacuum Tube Preamplifier (fully Assembled W/ Ge 12au7?s) TU-8500 | eBay

I would like to know if anyone familiar with the circuit, if they can tell me if the phono pre-amp circuit bypasses the tube section or does it get buffered by the tube section?????

I think it would be pretty neat to add some tube warmth to the OP amp processed sound. Sadly I cannot find any schematics or reviewes that go further into detail.......

Any help or directing would be greatly appreciated!

Just finished building my TU-8500 kit, looking at the schematic, every input goes through the tube stage. I highly recommend this preamp! I'm using mine primarily as a phono pre-amp.
