Re: uBITX - U1 Getting Fried - possible cause #ubitx


 

Should work fine, as suggested in post 42723 a few days ago:
? ? If really paranoid, perhaps add an 8 or 9v linear regulator (or string of diodes) to reduce Vcc into the TDA2822M.

Though I'd now tend to go for 6v, especially if you have a WX part.
Just because you're paranoid doesn't mean they aren't out to get you.

How about stacking a few 1N4001s in series in the power rail to the?TDA2822 ? Not ideal but could provide a couple extra volts headroom and easier to install than a regulator.
