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.

That's a pretty impressive store.

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.
