Hey all!

I was recently given an interesting power amplifier PCB based around a Darlington TIP41/TIP147.

I haven't built it yet, but since its a pretty simple circuit, I wanted to see if anyone had any suggestions for how I could make it work well as a guitar power amp?
Ideally, I'd like to experiment with making a hybrid amp.

Would this be an opportunity to add current feedback from the speaker? 

Could any of the component values be changed to help the response?

Or is it fine the way it is and I should just focus on the preamp?


Thanks!

The Newcomer's Forum / Super Basic Question for a noob

Hey all,

I just joined the forum and I'm happy to be here. 

I am relatively new to electronics.  I have built a few guitar and bass pedals from PCBs offered by PedalPCB, AionFX, PCB Guitar Mania, and a few others.  I have also done a couple tag board builds which were a lot of fun.

I am interested in learning more about amplifiers (tube and solid state).

I have always wondered something that might be a fairly basic question:

Is there a different between HiFi power amps and the power amp section of a transistor guitar/bass amp?

I understand the importance of a preamp and using the correct speakers and cabinet for bass/guitar, but I never knew if the power amp had different filtering or if it was all pretty much the same?
Also, if they are different, has anyone spent time building and modifying any of the HiFi power amps available?

Thanks and I look forward to explanations!
