Jerry,
Yes, 2n2222A are an oldie.? Ih 100 piece price range they get well under a buck.
True of a lot of parts.
For farhan its larger lotts a 50 board run that would be 300 2n2222a and a 500
peice or or larger buy.? As they say in the beancounter department, Wow ouch!
There may be cheaper solutions I have not looked that hard.? The MPSH10s
worked ok for the predriver and they are cheaper (I got 25 for $4.60) but they
were not that great for the driver.
Its not flat yet but will be way better at the bottom 3-4 bands.
