Re: Marconi 2022C - Stopped working below 62.5 MHz
BFR540 abut 43p at Farnell in singles 500mW and 9GHz
You might want to add a bit of base spoiling resistance just to have a component to cal it if it feels a bit too frisky, but this will still have hfe around 9 at 1000MHz given the age of the hybrid, I'd think something like a BFR93A die might be in the original. But we don't want something like the original because they keep dying.
