TNBC-0029 Issue 1 Sept 08 Technical Bulletin Issued by: David Drewett, Service Manager. Email: Telephone: +44 (0) 207 551 5403 Audio Partnership Plc. Gallery Court, Hankey Place, London, SE1 4BB Tel: +44 (0)20 7940 2200 Fax: +44 (0)20 7940 2233 Product : Azur 840C and 740C CD players Page 1 of 1 Fault Symptom: Low gain or no audio output on one or both channels. C270 on the 840C , or C5 on the 740C DAC PCB may be visibly damaged (top pushed up). Relays RL1, 2, 3 may not close. Cause: The unregulated 10V supply on these DAC boards is smoothed by a 470uF capacitor, rated at 16V. High mains spikes and supply fluctuations can cause premature failure of the capacitor. Solution: Replace this capacitor with the same value, but rated at 35V. We advise that you make this modification to all service returns. n.b. Production from September 2008 will be revised.
