Tristated output to two common Base transistor issue

[RussMartin]

Luciano: After testing my circuit on a breadboard I have found out
that the circuit works, but the current available for the LEDs
is too low for your application where the forward current of
the LEDs is 50mA.

Roger: I made the circuit too and yes, available current is far to low...

Is it possible that the series base resistor (2.2K) is too large? The "brute force" method to assure that the switching transistor saturates is to give the base about ten times as much current as it needs to turn on.

Remember, the base current controls the collector current: Not enough base current means not enough collector current. Try 820 ohms, then on down (680, 560, and so on) until it works.

I did a little looking on line. Is this the kind of thing you are doing?
