in the power supply 2*5A/24v relay what its mean?
is it one relay or two relay can anybody explain this .

hello sir apex can u share this power supllies in pdf or image pcb layout

Hi Apex!
I have 11V ofset 🙁
How mV must have of 0.33ohm rezistor, of one rezistor?

Input GND is not connected with amp GND on pcb, and must be connect to PSU GND if you want to test amplifier. Set 10mV on 0.33ohm for 30mA bias.

PSU on this pictures is not my.

Work! 30mV ofset! Nice Work Apex! Tnx for help!
Respect! i post pics but not now.

I like coment about sound, compareing with other amps..., and what is your speakers?

HELLO APEX SIR
CAN I USE THIS PSU-PROTECTION WITH THE SUPPLY OF 36.0.36AC SECONDARY .ANY CHANGES TO MADE?

FOR AX-14 THE POWER SUPPLY ONE PAIR 4700/63V FOR ONE CHANNEL ENOUGH OR ONE PAIR 10000/63V?

WHICH PSU/DC PROTECT U RECOMEND FOR AX-14 .

 

[jorjbg]

Apex, i cant test now. My speakers are bad, but after few days i test it. Now i test on one bass speaker, just for test. Tomorow i assemble and second channel, and i post pictures.My components are not so good...

With 2x36V AC only use 1k/5W instead 1k2/5W.
For AX-14 use one pair 10000uF/63V per channel, and I suggest Regulated PSU.

OK, good luck with second channel.

hello apex sir
can i use this regulated power supply with 36.0.36vac for ax-14?
any changes to make .

hello apex sir
can i use this regulated power supply with 36.0.36vac for ax-14?
any changes to make .

For 2x36vac use 10000uF/63V and ZF 7,5V instead 12V. Set +/-40V DC output voltage.

hello apex sir
can i use this dc protector for ax-14?
in this ptotector what is DB3 IS IT A DIODE? WHAT IS THE COMPONENT NAME OF DB3?

 

[wattaniya]

HELLO APEX SIR
WHY U SET TO +-40V IN THE REG PSU. AX14 MAX 50-+.

DB3 is a 28V, 2A, DIAC, a diode for alternating current.
As stated by Mile formerly, any DIAC is suitable for this application.

HELLO APEX SIR

With 2x36vac you have +/-50VDC, and you must set lower output voltage from regulator if you want have stabil output voltage without drop at amp full power.

Diac DB3 can be replaced with two TO92 thyristors BT169.
