I am searching for an Layout of a 10W output PA for my Transverter. I need
just one for 2m and one for 70cm. Has anyone a Layout or schematic to
build
it on my own ?
==========================
Suggest you consider Mitsubishi RF Power modules (still available)

for 144 - 148 MHz : M57713 P(max) =
10W (for linear duty)
M57719
P(max) = 21 W
M57715
P(max)= 20 W
or Toshiba SAV17
P(max)= 25 W
or Motorola MHW612
P(max)=25W

For 430 -450 MHz M57716 P(max)= 10
W ( for linear duty)
M57729
P(max)=?
or Toshiba S-AU4
P(max)= 10W

Not all the modules might be suitable for linear operation (SSB) so you have
to check with supplier.

Here in the UK a supplier still carrying these Mitsubishi power modules is
Mainline Electronics - Leicester

An excellent book for homebrew transverters and power amps with the above
modules :
