aa14, the connection of C12, C13 & R5 into the Signal Return does not look right.

 

[prasi]

Yep. I thought so too... But since APEX sch called for that, I made the layout accordingly.
Mr. Mile can only clarify.

Looking nice Prasi! I actually have all these parts on hand. It would be a fun quick build.

Thanks x, It would have been much more nicer if my laptop's mother board hadn't burnt. Its gone for repairs , so helpless.
Thanks for your appreciation.
I am waiting for Mr. Mile to have a relook at his sch again because of the concerns raised by AndrewT.
Once my Laptop is back I can rework to improve it.

Prasi, I'm interested in your aa9 class A and I think I'll be tempted!

Salut Project16,
Sure Mr. Mile's AA9 looks interesting. But I am not as capable as some of the builders here. So I post my layout for such active gentleman.
Do let me know if you decide to build and I will help in whatever way I possibly can. .

OK, I go to realize it because I like these TIP and we'll see. For the printed circuit I will use the .pdf files because it is not a problem for me to make them myself.

True diya spirit, I congratulate.

Mr. Mile, I know you are a busy person handling so many threads and requests by builders, but a small request; Could you kindly take look at AA14 sch and layout ? and subsequent comment by andrew T?. My laptop's burnt, I will rework AA14 whenever its repaired... Post no. 9423 and 9424.

Input GND on AA14 must be connect to power GND from input therminal... like on AX14.

Too bad about your laptop dying. I and through that last year and it was no fun. Good luck getting back up.

I've been reading this thread with huge interest but I lost myself in all the different versions of the amps posted.
I suppose there is a logic in the naming of the versions:

AX14
AX17
A30
AA9
AA14
...

Would anyone be so kind to explain the difference (AX for class AB, AA for class A, ...)?

 

[Kay Pirinha]

Yes, this thread has derailed from it's topic heavily ...

Best regards!
