Re: 300W BLF278 PA 48V (PA0V Nanko)

Hello Readers, I have just joined VKLogger following a suggestion when I found that the VK4DD online shop had closed.
With the close down of Analogue TV in New Zealand our club the Auckland VHF Group has received some surplus VHF TV amplifiers containing a device similar to BLF248. These amplifiers use a PCB that is too frequency concious to convert to 144 MHz.
Does anyone know how to purchase the single device VK4DD design for the BLF248? It would allow us to take advantage of the device and metalwork to make a nice PA for 2m. I have had information about the dimensions so know that the PCB will fit the metalwork.
Regards, ZL1UKG
