This is actually not a project made by me, but nice work made by OZ1CT
I was lucky to buy below gear, as OZ1CT decided to build a water cooled PA based on two BLF188xr.
This is the amplifiere I curently use for 144MHz.
It´s a Harris Platinium TV-Amplifier that used to be in service at TV channel 6 (around 85MHz), but been rebuild by OZ1CT to 144MHz.
OZ1CT Bent have put full information about nice work he have made on the internet.
