Studio Reference Amplifier

[apexaudio]

Hello, I have another question, it may be simplistic for many members, but for me to understand better how the protection works: is the PRO input of the protection circuit simply connected to the output transistor emitter? So this way in any amplifier is it possible to connect a protection circuit? Thank you and I hope to solve this doubt because I want to put a protection on an amplifier that does not have it.

Only this protect can be connect to the output transistor emitter.

Yes, the protect circuit measures the voltage across the emitter resistor.

Still4given thanks for replying,

All the best!!

Mile, thanks again for your help,

All the best!!

Best replacements for bc550c/bc560c?

Do all the protection circuits developed by Mr. Mile protect against high current, short circuit and DC voltage or only against high current? I want to add to my amplifier only one circuit with all these features if possible.

Sorry, I wasn't specific. Does this protection act against short-circuit and DC voltage or only against high current?

SR150 plates almost ready, some tracks need to be corrected with the micro grinder that were amended with the pen correction.

Looks good.

Awesome! Great sounding amp.

Here's mine.

Still4given, congratulations, very curious to hear what the sound is like. I intend to make this amp my living room.

Hi. Can this circuit be used for 110v?

I have tried to create this SR55 PCB layout. Mr. Mile Please check.

Dear Gurupreet,
It will be easy for others to check if you also post all your project files ?

Hello Gannaji, I have only SR55 sprit layout, no multisim or other simulation file. So I just post only Sprint file.
