Is there 18R instead 180R on your pcb?
Mr Apex.can i use Bc546 for Q7?
Hi Mr Gannaji,dear masood251,
Have you used "dim bulb tester ?"
gannaji.
How to use dim bulb tester?
How to connect and what type of bulb can use?
Is there 18R instead 180R on your pcb?
Sir 180 ohm is connected emitter of BC546 and connected with negative via 10 ohm resistor.thanking you.yours.
pdf please sr prasi
PSU 10R AND PSU 15 , done deal!..😀
Same mounting hole distances maintained. Also given pads for output devices PSU10R, if anyone wants to run wires to heatsink.
regards
prasi

@gannaji or anyone: If using a Variac, would you put the bulb tester between the Variac and the unit being tested, or is a bulb tester not needed if using a Variac.
Prasi, I will follow your FH9, as I have a set of CFH9 boards I have tried to sell, but may have to build if no response to sale.
Be safe everyone

That bulb tester is your single best safeguard to protecting components. I use both every time. Without the bulb tester stuff can burn up at low voltages if something is wrong.
Can anyone tell which is the best apex amplifier with good sonic character ax or sr or Fh or x with low noise good sound dynamics

hi dear friend.i have aproblem with apex 555 problem.i download many layout of apex555 protect mono and stereo...and made but dont work....now i find correct schematic.
plz tell me apex555 have overload/short circuit protection alone? or need add sepreated overload detector...?
(i buil ahmed yerli complet protection but it have not fast action when turn on power and relay dont act together.)
i want use apex555 pro with all of bjt and mosfet amp like as ax14/ax17/fh11..if it have overload and short circuit to...i know there are many apex protection but i want use apex555.
i wait for reply..with best wish for you.

sorry again....about psu 10 ....is it for high end guallity sound?
will you pleas share complete circuit pdf ..schematic along with base treble and power supply unit

AX16 is AX14 with add overload/short circuit detection PRO adapter. Reguleted PSU15 is for any amp.

Nice Layouts.

tnx mr mile.i buil ax17 its very good quallity.,and now need a full protector...need to add overload detector for apex 555?
if yes..tell me to add and design a new version af apeex555.i do this.

Hello prasi and Mr. Mile, I've changed power transter with TO-264 package and track change by rotating MJ15030. Capacitor removed from Layout because I have allready simple PSU.

very nicely done!..congrats...yes, this one can be used when you already have simple bulk PSU with caps. Even I have such simple PSUs and I could add this regulated PSU as additional.
You could slightly move away the output transistors so they dont foul with V+ and V- faston connectors..
