I do have build other amps like the said famous threads with ten of thousands of hits.
They are the baseline for classic designs , otala (symasym - subzero) , RCA (dx-aksa) , Linn (self - quasi).
Dr. Bora is not afraid to use more CFP inputs or other "finer touches" in his designs. The classics are good (and sound good), but can be refined with better auxiliary circuitry and better/faster parts. I notice this looking at my "bora" schema collection.

What is going on with your WEB page...? There were a nice compilation of good schematics and other useful stuff. I can't open it any more...

If you want , i'll let YOU have full access. It has become quite large.
Just give me some of your newer designs.

That could be arranged but condition is that they are JUST and ONLY for your eyes regardless of anything!!!
PM me , I will give you web address.
I would never copy someone's work. My "supersym" is not M. brittners "symasym" , it is more influenced by Otala , hitachi , and any other worthwhile idea I have been shown. My goals are not commercial.

dear dr bora
greetings i want to make omni dc protector can it be used
ith a hexfet amplifier av 400 anthony holton design mainly interested in less than
2 ohm protection will it work for this amplifier
thanking you

Of course it can... with ANY modern amplifier with split supply and complementary output stage. Some components values might need tweaking in any particular case because they depend of used PSU voltages and output power.
OMNI protector is undeservedly rarely mentioned in threads dealing with that type of circuits. It is a very good and universal solution. You can find it in this thread (several consecutive posts!!!):

How did you come to the PCB intensified when you did? How you come to them at all?
English please.

How did you come to the PCB amps when you do? How are you coming to them?
Is that question for me Dadi55?

Check your mail for PCB files!
hi All,
anyone can tell me what type of PS should I use with these TDA amp? I was thinking of making SMPS for it is there anyone has SMPS design and PCB layot files? Please share

New boards for Sigma amplifier. Waiting for parts to arrive and to start composing the amplifier. Power supply will be + /-48V DC.

Hi viktor this is a nice board. Do you have any regulated power supply PCB and diagram? I need it for TDA 7294 amplifier.
I have not made regulated power supplies, all of them were classic. Here's two solutions for you

Viktore,
In the original Sigma schema the power supply is set to dual 68V and the output is 130W RMS / 8 ohms. With a power of 48V what would be the output?
I want to start with some of Dr. Borivoje amplifiers, some with high quality and no more than 80W / 8 ohms. Having said in mind, is Sigma good candidate (I know that Dr. Bora have some non public better amplifiers hidden B-)) or would you suggest something else?
Also, if in your opinion Sigma is good, can I have a PCB and layout as well?
Hvala, Marin
