R 70

Audio Upgrade

Kiwa offers an audio upgrade kit to improve the audio quality of the R70 receiver. The audio upgrade kit replaces capacitors in the audio signal path with types that have improved sonic characteristics. The capacitors in both AM and SSB signal paths are replaced. The end result is that consonants like k's, c's and q's will sound sharper with improved definition. This improves the overall intelligibility. The kit comes with instructions. Soldering and desoldering experience is required. No alignment is required after completion. Kiwa also offers installation of the audio upgrade if you do not feel comfortable installing the required components.
