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. :D :D:D The 2-step version has been working fine for gigs over the last 4 years.

AutoClass where is your schematic with values of the components?

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 *****.
