[quote author="khstudio"]I just ordered 2 of the 1176 new design boards & haven't read the GIANT thread yet & was wondering if I may need to match the FETs for that project also :?: [/quote]
I think PRR suggested a test circuit for the 1176 somewhere here, which basically rebuild the 1176 damping section and used a pot to supply the control voltage for the FET from a battery. I measured the control voltage for a damping of 1 and 10 dB and selected the closest matches for the gain reduction FETs for stereo pairs and the 2nd closest matches for their gain reduction meter FETs. I got FETs for 10 units out of 100 FETs I measured, but haven't finished the units yet, so there is no sonical confimation yet. But I feel very comfortable with that method, because it basically does, what happens in the real unit anyway.
