Re: uBITX - U1 Getting Fried - possible cause #ubitx
Recently I found some TDA2822's on ebay from China, I got the GQRP club to purchase a batch ( I bought 50 too ). Tony Fishpool (G4WIF) setup up a test and found although they worked well at low Volts they got hot over 7V!:
His findings are made public here on his website here: http://www.fishpool.org.uk/audioamp.htm
Food for thought!
