Re: Amplifier
Hi!
I'm building one LEGEND amp at this moment, and I'd like to ask how does it sound?, did you make any modification to the circuit?
I can get the IRFP150 MOSFET transistor at U$2, the IRFP250 is double the price, which ones should I get?
I'm building it to drive 2 - 15" 8 ohm sub speakers
Anyone have tips/mods for this amp?

the 20pF mica cap is in wrong place... that need to be between the VAS-transistor's base and collector. that's the miller cap.
am I wrong?!
Its not wrong , its just another VERSION of VAS compensation technique apart from traditional types...
