Nice initial results there Tony. Looking forward to completing the Colorado Tsunami Project, thanks for leading the way on this build and smoothing out the speed bumps along the way.
That makes some noise . Needs to be in a soundproof room. Very slight cross over distortion. may be just a bias setting. Takes some testing and adjusting to get it right on. You need that Bird 10K load now. 73
Yeah it needs some minor tweeking. The bias voltage needs to be a bit higher right now the no signal bias current is at 0.4A and the circuit calls for 0.6A
