T_Shomaker Posted December 12, 2003 Share Posted December 12, 2003 I just bought a pair of heresys of ebay for $375 and they are awesome. But I have an older Yamaha A-420 Integrated Amplifier and I need to know how powerful it is. So I was wondering if any of you guys had one of these amps and knew how powerful it is.

JohnA Posted December 13, 2003 Share Posted December 13, 2003 I don't think it is near 50 wpc. My CA-800 was 45 wpc in Normal and 8 wpc in Class A. I'd guess 20 wpc; more than enough for most music through La Scalas. Quote Link to comment Share on other sites More sharing options...
JCturboT Posted December 13, 2003 Share Posted December 13, 2003 http://www2.yamaha.co.jp/manual/english/download.php?div=av〈=english John, I would say Busa is correct about this Integrated amp. I could not find any info this particular model at the Yamaha site but the blue book does list the A-420 at 50wpc.The A-520 does show at 75wpc so that makes sense in the Yamaha scheme of things. If anyone owns a Yamaha product most manuals can be downloaded at the above web page. Jeff Quote Link to comment Share on other sites More sharing options...
