Sacrificial power darlington?
For an audio amp that may have catastrophic oscillation problems. If you
combined TIP3055 and TIP41C (say) , with biasing Rs of 40/ 8K scaled for particular use, plus a power diode, would that give you a functional power darlington. And more so in this case TIP2955 and TIP42C to stand in , for initial proving purposes so heatsinking not a great problem, for an expensive pnp power darlinton. |
