Re: New uBitx 6.1 - Have I already blown the finals?

Before you pull the finals, run the bias adjustment calibration.  If you get the 200 ma change from receive to transmit without any audio (NOT CW), then most likely the finals are OK.  Here is the tuneup from HFSignals:

If you cannot set up the bias, then the finals are most likely blown.
