I'd like to ask, what exactly is the "ULAZ" that can be seen on the second image?

I'll be building this amp this week, and I'm curious to know what that is.

@ apexaudio,

Thanks a lot!

Can this amp be connected in parallel to other amps so that we can obtain higher power?

Cheers!

This PCB draw by "Corel Draw 12" It's harder than "Protel" but with more posibility.
