At least, those 10% donated should go to the right person.

Apex shared a lot of amplifiers under the general title 100W ultimate amplifier.
This ax14 is one of those.

Hello Selwe,
Its an Apex AX-14 amplifier with 2 pairs of o/p. Some people have built it.
Yes, if one orders PCB online from PCBway, then 10% (1 usd) goes to my credit🙂

Hello Selwe,
Thanks for your kind words, and appreciation.
I have seen people who pay me paltry sum for custom pcb designs.
I may have spent 10-15 hrs in designing pcbs as per their specific requirements, they pay me less than my day's job. shame isnt it? 50 USD payment as if they are doing me favor!
I get more just doing my company job, whether I work or not on some days!😀.

I simply need to get more business minded and charge upfront.

regards
Prasi

Very Nice Aleks..Well Done!

 

[muz1ca89]

I have a problem with the relay does not switch and on the signal led I have 12 volts.thanks

 

[avtech]

😕

You need to explain the problem clearly otherwise no-one knows what you are talking about.

What amp/preamp/protection module?
What is the issue?
What have you tried so far?
Clear photos of both sides of the board.
Schematic is always a plus.

etc. etc.

my atempt of AX30,IS and VAS,in progress;

 

[44250]

NOT TESTED YET!!!

NOT TESTED!!! to achieve as short traces as i could and to thermo-couple all needed transistors,i had to separate IS and VAS board from OPS board,so now it looks like this:
