Not sure what will the outcome be (never tried it). I just want to make
this TV center close to all other regular oak finishes furniture. A lot
of them are "smooth" feel, yet little grooves by the pores. I don't want
to make the TV center shining gloss, extra smooth. Just to blend with
other oaks in the living room.

When you say try Watco first then finish with Waterlox, you mean that
extra link below or there's a clear coating?

No body mention if I should use spray? It is going to be huge work by
hand, but I still can do it if necessary.

No, it's not quite as amber as Watco Golden Oak, but it looks great.
Try a single coat of Watco and finish up with Waterlox.
