Dear,
Anyone experience with those driver transistors?

2SA2219 seems to be a cheaper variant of the 2SC5171 (same Cob, similar voltage ratings), but with only half the transition frequency (100 vs. 200Mhz).
As you can easily mount the 2SC5171 onto the main heatsink, I personally prefer these. The high fT with the low Cob makes it a nice VAS-transistor too.
Have fun, Hannes
