How to Use Power Transistor for TDA2030 Audio Amp?

08/27/2021 5:00 AM

Good day, all

Recently, I am attempting to make a Stereo Power Amplifier using two TDA2030A.

I want an output of at least 25 watts per channel. The datasheet shows me that I need to add a pair of power transistors, BD907 and BD908 if I want my amplifier for higher power output. There are two circuits shown below and the one with the power transistors outputs more power. My question is this. Can I replace these BD907/908 with TIP35C and 36C , which are more easily available?

I have purchased a transformer of 24V-0-24V, 80VA.

Anyone has ideas of it? Many thanks!

Shirley you jest....

Why do I get the feeling some unknown expert is going to chime in here singing the praises of some chip....?

Here is a cross reference for the BD907, ...08.

And for the TIP 35C...36

Looks like they are a compatible exchange.
