So I know that with capacitors, its easy to upgrade or replace a capacitor based on its specification ( voltage, max operating temp, ESR, Ripple, etc, etc).
But what about diodes and transistors. What values can I exceed or lower and not blow up either the part itself or parts around it?
Looking at the data sheets on diodes and transistors there are so many things listed and measured. Its kind of a big pill to swallow for a newbie.
Thanks in advance!
Don’t bother. It’s unlikely that it’ll actually make a noticeable difference in the output sound quality, unless you actually change the circuit diagram.
If all you’re looking for is higher output power, you will need to buy parts with the same specs (same forward voltage, resistance, source-drain, gate-drain, etc.), however, with a higher output current. You will also need larger heatsinks/more airflow, to deal with the higher current draw.
Along with changing most of the components to allow for higher output power, you will also need to increase the trace size, to reduce the voltage-drop caused by the higher current. That will be the difficult part.
It’s not worth the work. You can buy used audio amps for really cheap now-a-days.
