Small AMP for QRP Transceiver

I purchased RM Italy HLA-150 Plus to get reasonable power with QRP Transceiver. It is 191x290x66 mm and 1.8Kg.
If it works with 130 to 150w output together with small/compact QRP Transceiver then
it is ideal for my DX Vacation.

I simply made input/output measurement with dummy connected.
It is driven by K3.

As you see 3 to 5 watts input is enough to get good output (120 to 140 watts) except 14MHz.
I do not know why it is saturated only at 110 watts.

If I chose KX3 as small/compact Transceiver then total weight is 2.7 Kg !
