100W Ultimate Fidelity Amplifier

[AndrewT]

I suggested that ALL capacitors have pin pitch options.

in parallel = 9.4uF uhmmmmm ok lol

I change the 1/4 resistor to see how it look

I think this size resistors looks at lot better I think , before everybody jump on me I'm not an expert like mister Alex MM but I like to do this a lot, and I'm learning, I know some of you guys are expert and professionals on this that is for sure lol , I did learn electronics in the Army as 94F but fixing night vision equipment and mine detectors don't really match with audio lol so be kind I do accept my errors, I really don't mind at all. here is a draft of the layout not done yet because my father was really sick yesterday so I have to take him to the hospital, today he feels better thank to God, well guys have a good day for all of you.

Hi Juan,
Take your time and I think we should consider the suggestions of experts here like AndrewT. I am also just a hobbyist and an accountant by profession so I am just learning here with the help of the experts. Thanks.

Rey

what is the all registar watts size

 

[shravanth]

hello friends i have made AX-14 but it is not working. . . can any one help me plz.. . .

 

[AndrewT]

.......... consider the suggestions of experts here like AndrewT...........

I am not an expert. I too am a hobbyist, take pays attention to the details.
But getting the details wrong can ruin audio performance.

Post pictures, measurements...

 

[shravanth]

in the output i am getting DC

An externally hosted image should be here but it was not working when we last tested it.

 

[smartx21]

Are those 0.33 ohm resistors? Sorry for my humble knowledge.

 

[wattaniya]

for me 5w resistor is 33 ohm.
connect psu G to input G.

 

[Junie]

I reckon that 33E--->33ohms? I don't know really.

 

[wattaniya]

hi apex sir,
i connect the vu meter to ax14, the three lights permanently on. why is that.
supply voltage to the amp 50-0-50vdc.
here are some images.

 

[smartx21]

I use to test and measure every single part before soldering on the PCB. And also double-check polarities! This way, all is needed is power on and adjust!

 

[shravanth]

oh . . . . i have done a big mistake

thank u smartX they 33ohm not .33

i think that is the problem

 

[shravanth]

what is the transformer rating

Voltage-
Amps-
VA-

 

[wattaniya]

i am using ,transformer rate- secondary 36-0-36vac (10ampere) 720va.

 

[wattaniya]

this is my pcb driller.
there is a sliding bearing have, in the middle of the plywood, to slide top and bottom.

 

[wattaniya]

this is my pcb cutter, it is a angle grinder with diamond cutting disk. i made the jig.

oh . . . . i have done a big mistake

thank u smartX they 33ohm not .33

i think that is the problem

No that's not the problem, connect input GND to PSU GND and offset will be about +/-10mV.
