need a source and information on a 288-5336 audio amplifier IC

Dec 13, 2015 2 Replies

I have two audio amplifier modules I scrapped out of an 8 track player many years ago. I use these to amplify the headphone outputs of two PRC77 mili tary radios tuned to six meters, so that I can monitor on speaker. These mo dules fit perfectly so I need to retain them if possible. The modules put o ut about 4 watts each. One module is shorted and it appears to be a bad amp lifier chip. There are two output IC's bearing the above number in each mod ule. I can't find a listing for this anywhere. Can anyone help? Thanks, Len ny

are these DIP ic's ? and if so, what pin count are they and do they have the middle legs bonded together from the package?

I can give you a couple of numbers to look at to comparson.

LM380, LM377

etc.. Spregue made some direct replacements etc..

Take some readings off the pins of the working one, while it still is, and try repinning some modern replacement to the shorted one. On removing that , maybe some other number on the underside of it.
