TTech,

Must post pix to the board of your work. I'm glad the speaker is working, I can't wrap my mind around a Mason jar and a horn speaker Icon_think

May want to "stuff" the .3mf RF bypass cap. The paper one will be leaking. FWIR it is in a metal can with a soldered bottom. A .33/630v may be too large a diameter, three .1/630 in parallel may fit better. The metal case should be the other terminal. GL chas
