S2+ host build question

djozz,

Inserting a 2.2 ohm - 10 ohm resistor in between cell+ and the C1/D1 junction will fix the problem. (Stacking C1 is a brute-force method that fixes the symptom, rather than the problem. Tantalum is not great for this, too high ESR.)

You still want to feed the emitter directly from the cell+. IIRC the layout of the X6 driver makes this tricky, but I am sure you will find a way .

(On some drivers TomE’s ‘tombstone’ technique works well. Basically you build a little pyramid with Rnew+D1+C1 placed vertically, their junction up in the air.)

I tried it and it worked! Thanks DEL! What did you mod today? - #2183 by djozz
