Matching Mosfets For Audio Amplifiers !!

[@user-su5sq5ib3i]

I needed to match 4 fpq13n10's and ended up here. Thx for the video

Thanks for the great video!

[@JasonLeaman]

Glad it was helpful, Thanks for watching !

Sorry. I'm not sure, but is it possible that the annotations you made in pencil at minute 7:36 you made a mistake? I mean the N channel. I think you swapped S for D. Thanks.

Thanks a lot for the video, very informative. Do you also have a simple tip to match bipolar transistors? Thanks

[@TheZpilot55]

Thanks for the vídeo. Can I use a 12V DC source? I got one from a PC. Tks again.

[@aldogentile245]

Thanks for this great video. I noticed at 5:32 that Vgs began to decrease. Do you know why?

[@marks7663]

…other reasons like letting the magic smoke out. 😉

[@paulpaulzadeh6172]

very good , put more video

[@TheZpilot55]

Hi again. Is It necessary matching fets for a class A amp, w/ just a pair of fets? Like Pass ACA? Tks again

[@JasonLeaman]

No, you don't need to match for a single fet per side.

[@JasonLeaman]

Why not just use a 12v battery ?

[@dkerlee]

regarding matching MOSFETs in amps: at 7:29 you point out MOSFETs being "matched for the top" then MOSFETS being "matched for the bottom," then I thought about your tug of war analogy. Seems like not only do the four on the top need to match one another, but all those four ALSO need to match the bottom four, so 8 perfect matches in this example?

[@JasonsLabVideos]

You want the Tops all matched close together, then the bottoms all matched together, the tops don't need to be matched to the bottom, or VS versa .

Subb'd, thanks for showing me this.

[@dkerlee]

That is a really fancy multimeter and Power Supply Unit you got! Is it possible to do this with cheaper tools?

[@JasonsLabVideos]

You don't need a very fancy meter or PSU. However, the more digits on the meter the better for accuracy.
