Greetings from Sactown, Bill E. Only 398 audio mod performed was replacing the
stock audio caps to increase fidelity. As a side benefit, f.m. stereo
soundstage via headphones & tape out has widened. Grundig's YB-400 f.m.
performance, though aurally impressive, now sounds "flat" in comparison. Also
substituted Sangean's stock speaker for one from a Sony 7600G. You might be
better served removing that mw attenuator, which will increase 160 metre ham
reception as well. Best of dx from sactown-n-WA6020SWL!!!
