Further investigations will be made shortly. All currents drawn are within the specified limits. Tony.

Had similar fault, radio works but weak audio. Scope shows only one output transistor working but non-working transistor is OK. Output from driver transformer does not look very good, definitely not equal and opposite
. Suspect transformer so the whole thing will go into the junk box for when I need I.F. transformers etc.. No big deal, have plenty of LW/MW radios here, fun building apart from lousy circuit board with poor track adhesion.
