No there is no CCS's there is diamod buffer and there is no BD drivers there is BF transistors in VAS.
50x50 F8 by Sonal
Yes, yes i have seen the new F8 and would put it to a project to learn more
in Eagle CAD- and tje- sonal comes here after two days.....
Nice, i like it- the next in 50x50 class Amp. Wow so fast! 🙂.
Next step should be place an order- that needs gerber files too. 😛
Cheers Bangla.

Hi Mile,
thank you for your answer,
I don't really understand why 48vAC.... I need to learn more 🙂
I think this one is suitable

Hello Sonal
greetings is it possible for you to design single sided CFH7 pcb double sided
pcb is hard to diy
warm regards
Andrew

your 25-0-25Vac transformer will give you approx ±35Vdc.
that will get you roughly 50W into 8ohms.
Two channels comes to 100W total. You need a 100VA to 200VA to run that well.
If you use 4ohms speakers then your total maximum output power goes up to around 180W. For that you should use a transformer from 180VA to 360VA.
And to minimise the change in transformer voltage due to transformer regulation I suggest the smallest transformer for a power amplifier should be 160VA.
A 160VA toroid usually has a regulation value between 7% and 9%.

I have jbl1200w 12"4ohms subwoofer. Which amp for good and rail details
I think fh11 good for subwoofer .sorry for my bad english

ALFET FX8 Board
Yes Dobrivoje, with ALFET NP Type is real nice choice. 🙄
Soon one more 50x50 class amp. FX8 based on sonal kunal pcb.

100W Ultimate Fidelity Amplifier-fx8000.jpg
Never seen long time, because more than 1 or 2k was sold for one best known
Amplifier here.
Do you need a little heat sink for TO126 Transistor- runs more stable in bias
and offset- if they run to hot bias rises away- have you tested without cooling?
Mine are running with only 100mA 24/7 at moment.
Cheers Bangla.

I bought my Alf latfets at Farnell.
ALF08NP16V5 - SEMELAB - Dual MOSFET, N and P Channel, 8 A, 160 V | Farnell element14
BD139/140 will have a piece of alu plate.
I hope in a few days amp will be finished.

Look around this post for PCB files from Sonal.

Sorry for stupid question, but how did you get 50W?
I thought the voltage at the speaker was defined by the impedance of course, but also with the power of the amplifier and the power the speaker can manage.
Do you know good documents on Internet for my learning?
ps: My speakers are 8 ohm
