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

Yes, Raj, bridge mode gets you more, but likely more than twice! While one 'phase' is going positive, the other is going negative. W=E^2/R, double E (Voltage) gives double squared (4x) power. That was the impression I had gained from earlier discussion. More likely is the In/Out-rush current, instantaneous fubar! The heat and pyrotechnics would be after-effects. Less C for less Bass would be sane, a series R likewise - the few dB loss would hardly matter - Bitx-40's sidetone-at-the-speaker arrangement would be an indication...
