Suitable power amp replacement(discontinued)
Hi Folks,
I have a San Jose CD/MP3 car stereo that I would desperately like to repair. The part in question is an LA4743B, manufactured by Sanyo. The part is discontinued. It is a 45W, four channel(bridge) power amplifier in a 25-pin single-row plastic package(w/integrated heatsink). I am having a really hard time find this part because it is discontinued(unless I buy like 300 of them from an overstock locator). Can anyone recommend a replacement part? I believe these are used in Clarion head units also. If it helps, the Sanyo datasheet is at: http://service.semic.sanyo.co.jp/sem.../ENN6630_d.pdf Thanks so much, -Jamie K |

Try NTE's site. That was my first visit, no good. A parts and service center for Blaupunkt got back with me, they can obtain an LA4347K, not the 'B'. I can't find a datasheet on the K to do a comparison, but I'm going to chance it. It's $18, but I paid $280 for the head unit at the time. Worth the trouble/cost in my opinion. -Jamie |
