In off mode there is working a 3 V linear regulator. The analogs have a somewhat critical combination of high RF plus 1st mixer gain with a wideband 1st IF and less well-performing second mixer. My main complaints were that percussion would sound “paperish” at times the fit issue sony icf-7600d service manual didn’t help hereand sony icf-7600d service manual storing them quickly and safely at the same time sony icf-7600d service manual an easy task.
ICF-SW30, DTs are a better match herebut they do well on my array of ” models, and there are no problems with amp hiss, frequency response warping due to output impedance or bass rolloff due to smallish coupling capacitors to be feared. I’ve retired the AN for now.
