20000 watts per channel

hello
greetings just another example of transistors working at more than than their MAX RATED VOLTAGE 2sc 5200 and 2sa1943 max voltage 200 volts dc
here a chinese amp AB CLASS working at 120 volts dc+/- lol these chinese amps no wonder they are not rugged i will post pictures of the amp working with voltages
busy cloning the driver section
warm regards

Hi Sameer
greetings just be carefull many caps look exactly like resistors same like 1/4 watt resistors 22pf 100 pf 470pf scan pcb and take print out on tp transparent plastic then pcb will be easier to make
i know you like making pcbs you are good at it driver section sound quality is VERY GOOD
warm regards

2sc5200/2sa1943 is rated at 230V for VCE as per Toshiba datasheet. Correct this oldman.

Hi Workhorse
greetings corrected sir when you get old mistakes creep in someone promised a grounded collector amp schematic
WARM REGARDS

2sc5200/2sa1943 is rated at 230V for VCE as per Toshiba datasheet. Correct this oldman.

And due to Fairchild it's 250V !!!:View attachment 2SC5200.pdf

Mr. Microsim,
Good morning from India,
As asked by you a photo of some of the works already done by me, I cannot be in photo as I was shooting it,As soon as my 84 year old father becomes little well I will start my new projects, As for now my prime concern is my father's health.

 

[vedmitra]

One more view of my workshop, but as it is waiting for me since 2 months due to my sick father it can wait some more days for me to make big amplifiers.

@vedmitra


nice workshop, nice amplifiers also.


Please take your time, I wish good health for your father.


Regards

 

[vedmitra]

Well wishes of Holi

All the joy of life as those colores from me and my family to members and their family on happy HOLI

Ready for real work

Almost after 3 months my workshop cleaned and ready for work

 

[vedmitra]

ALPHA 1 in progress

All the 4 heatsink cleaned and marked with punch to drill holes and make thread to mount outputs for ALPHA 1

 

[vedmitra]

Alpha 1

More than 51 volt at out into 1 ohm with only 0.6% distortion full load more than 2.6 Kw.output with 16 pair 5200 1943 at only 80-0-80 D.C. Rail

After a long gap first project

After a long gap of almost 3 months started work in my workshop, I am not in the photo as I am the one who is taking photo.

 

[MicrosiM]

Very nice work vedmitra


Keep the good work

 

[vedmitra]

Thanks Mr. Microsim, now my father is better,He can walk by himself , so now I can start my work,most hectic job was to clean workshop and arrange components as space is limited.

ALPHA 1 Taking shape

ALPHA 1 Taking shape slowly, All 4 heatsink mounted with outputs and drivers,9 s.w.g. copper wire scraped and sanded for negative , positive rail and speaker out, 16 s.w.g. for base and vi limiter

Nice amp and BIG amp

This looks massive power for me. how many KW is this version?
