Hi, all
Recently, I am attempting to make a Stereo Power Amplifier using two TDA2030A (data source: https://www.apogeeweb.net/circuitry/TDA2030-application-circuit.html).
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.

The TIP parts have higher ratings and should work without any obvious issues.
