(Somebody said that cap there was none). I see a 1uF cap instead of a 2.2uF.<br />Anyway, the most important thing I wannt to get is: LED and the BAT41 clipping should be confirmed, but what about the central position of the clipping switch? Mosfet or no diode mode?Elijah-Baleyhttps://www.blogger.com/profile/16374916649117645180noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-39153593920473685052019-07-15T10:43:45.302+01:002019-07-15T10:43:45.302+01:00Oh that makes sense now.

It's for this build and another. This might be off topic but a capacitor with markings U10nJ2A was included. The "u" was kinda written very small like a superscript. Do you or anyone here know the value of this capacitor? Didn't get any result in google too and tried to contact the seller but didn't get any reply.jrdnhttps://www.blogger.com/profile/05277146659870623754noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-91814863869388530722019-07-04T11:38:25.819+01:002019-07-04T11:38:25.819+01:00Thanks.Thanks.jrdnhttps://www.blogger.com/profile/05277146659870623754noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-11945802601060451922019-07-04T07:56:44.627+01:002019-07-04T07:56:44.627+01:00Exactly, and the 4.7k on the LED+ stripe is the re...Exactly, and the 4.7k on the LED+ stripe is the resistor that control the brightness of the LED.
