The Professional Class-H Amplifier 2KW

[AutoClassA]

Part Values

No complete schematic (values and all). ??
OS

Schematic *IS* Complete, But without part values, for refrence only...
Until now 🙂

Output stage can accommodate variety of pairs, I prefer MJL21195/96 pairs if an increase in output is needed.

hi workhorse
greetings can you tell a direct replacement ic for IR2117 very hard
to find or any site wich has 3 step using LM311 AND 2N3904 2N3906 transistor
easy to get and cheap .
thanking you

Has schematics for the 311-based circuit. The project and many others have been on hold due to a severe lack of shop space. Everything's in storage - I had to tear the building down and it just now being rebuilt. Then the amp work re-starts. 😀 😀😀 The 2-step version has been working fine for gigs over the last 4 years.

Nice Amplifier, Good Work.

AutoClass where is your schematic with values of the components?

 

[Dacuycoy]

i think this is for sale so no values for the schematic... business 😀

Anything bad in selling pcbs?😱

 

[rhodrich]

Im interested on that pcb im from philippines 2 units how much the price

 

[coolet]

In that case this thread is worthless here and should be moved to the commercial section.

Parts List with full detailed schematic will be accessible to those who will buy the PCB.

PCB cost is around 45~50US$, excluding shipping, While at least 50 PCB orders are minimum required in order to run the group buy.

Also Group Buy will be started in a few days. can be followed here

Anyone building amps with this kind of power should already be able to calculate the necessary resistor/cap values and spec the transistors. If you can't you're asking for a pack of trouble. You don't need a degree in electrical engineering - just some experience building amps. If you want to blindly copy something, copy something smaller until you get a handle on what you're doing. Electrical fires are a real *****.
