Homemade pcb for AX-11 with TO-3 outputs. Original pcb design by Willy B. Cerna, with some modifications.
An externally hosted image should be here but it was not working when we last tested it.

Hi, Sir Apex, can i do like that?

Nice
really a great result you used toner transfer?
It looks like it was made with photographic process
I was very eager.... let's start with next Apex.. Thank you mr. Mile for this kind of fun...Sir Alex, Thank you also...

AX-14 Testing,
I started testing my AX14, set up bias to 15mV, and DC offset is 2.5mV. i have it with my bulb tester and no light stay off. connected an speaker and sound is good. however when i measure the output power i use a 8ohm dummy load when I pass over 14V of power the light bulb tester lights up, turn the volume down under 14V and lights goes off. Any avise to troubleshoot will be appreciated.

The Mains Bulb Tester is a damage limitation device in case one has made a mistake with wiring.
You do not use it to bias an output stage.
You do not use it to test power outputs.
You have keen eyes, at following schematic on pcb layout.
Completed layout of A4 last night.

Hi Sonal,
Very nice layout. Has it been tested by you or anyone? If so, what is the impression?

It just simulated
I built several amplifier base on simulation. Almost all of them can work at first built. It need some tweaking to make it perfect.
You can build another amplifier from me on my blog here. But, it use Indonesia languange.
