use any protection and instead relay put a resistor. than the voltage on it use as protection signal that will turn something on/off.

and if the driver is set to a 10mA bias or a 50mA bias then To220 temperatures will be very different.

thanks friend for your answer
i want to conect this protection to my micro project
this three board must be seperat of them
i have 5 amp in one box and i must have 15 protection for those
for every one amp 3 protection:
1. DC protect
2. over curent protect
3. short circut protect
i need 15 optocupler for this 15 protection
sorry for my english
are you underestand?

Excited to give this one a try...just etched my boards...

Nice design sir RIFF, can i have the pcb design of this amp sir?
Thanks!

hi apex sir,
maximum how many output pairs can i add to ax14? because i increase bias emiter resistor voltage to 20mv, outputs are little hot. can i increase the dc voltage to increase power.? any changes to make.?

Use AX20 schematic and add 2 more pairs ( 4 pairs total ), DC rail voltage with 4 pairs increase to +/-80V and you have 400W/4R amp.

hi qq12e5k1,
can u share this layout in pdf format.

 

[Riff]

for add more output

hi apex sir,
is this correct sir ax20 with 4 pair.

 

[AndrewT]

is ax20 the same as ax14, the topic of this Thread?

Yes it is at same thread http://www.diyaudio.com/forums/solid-state/164093-100w-ultimate-fidelity-amplifier-92.html#post2758526

AX20 use +/-60V rail voltage, I won't share pcb designs in future.

hi apex sir,
which protect u suggest for ax20 with 4pair 80vdc.?

Use protect from B500 or simple protect with NE555.

New Performance My AX14

thanks to APEX and Jhon Bali for PCB design. AX14 I use Protect from B500. I prefer character AX14 for my home.
