Am trying to repair an old 20watt amplifier, and it contains a small 8 pin I/C. I'd like to replace it but cant find it mentioned in the stock lists of local suppliers . It has the letters LF and in the next row 353DP, underneath this is the number 8543. Anybody able to point me in the direction of a replacement?
Thanks:D

LM353

Thanks but LM353 does not seem to be available here in NZ, tried two suppliers and it is not on either of their lists. Have you another option?:eek:


14.30 Sorry 'bout that! Had another look and found it under TL072/LF353. Will obtain it next visit to the 'big smoke':eek:
regards
