Folks, here's what I found out that killed the problem.

On the PS Vane WE 300B Replica tube there's a brass pin protruding from the black base of the tube (horizontally).

What it is for, I don't know, maybe part of the original Western Electric 300 tube design.

I contacted Suena at Mingda, and after several emails back and forth, she said I should cut this horizonal pin off with diagonal cutters.

I decided to file the pins off.

Bingo! Tubes go into the socket neatly.

Why didn't I think of this? Because they appeared too high up the black base to cause a problem.

Man do these tubes sound good.

Thanks to all for your help.

  I find that inexcusable of the manufacture to make a unit that uses 300Bs and won't use the original 300b that all had that guide pin. All Western Electric 300Bs had that pin. 300b tube sockets used to have a metal sleeve with a slot in it to prevent the tube from being plugged in wrong.
  
  This picture is of a modern 845/211 tube socket. I show it because it has the guide sleeve I am speaking of.
  
  It looks like your preamp has a "beauty ring" causing the problem.
  
  Again, inexcusable of the manufacture.

      When was the last time Philips made capacitors? I thought they sold that division years ago. Strange to see them in a new product.

        The amp in question is a Chinese product. What more needs to be said? My 211 SETs have beauty rings too, but they'll accept any properly-constructed 211. Sorry, I don't have a lot of sympathy for this sort of thing.
