Hi All,
Russian GU43b works up to 100MHz and it is equal 4cx1600 tetrodes.
It runs 1600W easy, 2 kW is possible also. Its price is $65, the price
of its original socket is $90.
Another  not  very  known  Russian tetrode with bargain price is GU34(thirty 
four)b,it is
able  to  run  700-900W  ,  sockets are also available. It is close to
GU74b.
