Default eBay LM3886 parallel kit

Has anyone tried this kit?

120W 120W LM3886 Dual Parallel Multicenter Amplifier Board Ref Jeff Rowland | eBay

Unfortunately I could not get a schematic, which is quite common on eBay.

This is for a friend of mine, not for me. I did buy a MyRef clone kit from eBay some time ago, which did sound very good.

A kit without assembly instructions?
Or is it just the schematic that is missing?

The schematic is missing and/or they do not have it or do not want to show it.

AFAIK the kit is assembled, so there shouldn't be any assembly instructions.

You'll probably still have to adjust those 10-turn pots. I assume they are for nulling out the voltage offset differences between the different LM3886es.

The board should at least come with assembly/use instructions and an adjustment procedure.
