8220 board mods. What is the capacitor value? #433

8220 board modification reference photo didn't make sense to me, so I drew a schematic by hand.

Is the schematic in the photo above correct?

If so, what value should the CAPACITOR be?

Any advice would be appreciated.

Hey, I picked a random ferrite I salvaged, and the caps look like some 220nF I had plenty of at the time. Looking at my soldering work, it would be more important to completely bridge the 0 Ohm R59 resistor to ground. Even a 0 Ohm resistor has a very small non-zero value.

Thanks for the lightning advice. Can I organize the schematic as shown in the photo? 20230309_213454 copy 2

You need to remove the R58 resistor, of course. But then yep. Edit: Ie, FB replaces R58.

Thanks a Lot!
