Hi, folks Recently, I am attempting to make a Stereo Power Amplifier using two TDA2030A (datasheet 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.
Is there anyone have ideas of it? Thank you in advance.

Accordingly to the datasheets TTDA2030 and TIP35C, from their SOA, on page 3, shows that the latter seems a little bit better than the first one. So, electronically, that substitution seems safe. But otherwise, such as noise and other characteristic, that criterion alone is not enough, and I couldn't tell.
As for the link that you supplied, it seems to be a 404 error, in Chinese or Japanese. Sorry, I can't get any of the intended info.
