Default Re: Wireless Set 19 Mk3 transmit.

hi keith,
it is oscillating , when i put a 4000 ohm headphone on the audio pin of the 12pins output connector the tone is gone and can hear the hf audio coming in,
not that good of course, the tee peak filter and maybe the valve components needs attention, the speaker in the audio stage is 4 ohm, i dont now howmuch this extra audio stage things can messed up, work to do
