Hi,

we are planning a M2 operation next cqww ssb.

we will use single coax stub based in k2tr design but can we install coax 
single stub direct at PA output???

It depends on the design of the power amp. See k9yc.com/Coax-Stubs.pdf Also, pay careful attention to the effect of Velocity Factor for your coax when cutting and trimming the stubs. This is also discussed in the link.
