SOIC or DIP?

I do not know what the alphabet soup at the end if the part number means

It is a "cn" commercial rating, which for that part is 0 to 70C temperature rating. It is only available in a 16 pin wide SOIC package. In a pinch a 14 pin quad op amp could be used and 8 and 9 pads can be connected to a band-gap reference IC.

Yep, looks like you could make a replacement out of a LM324 and a LM385 (the 3-terminal adjustable voltage version, not the 2-terminal preset ones)

gotta love it!
Thanx Steve...I just love it with all the knowledge out there to draw on. Being involved in present day electronics certainly gives you a cool advantage. We'll just install the 14 pin ic & then just use the open holes at pins 9 & 10 for the diode. It'll almost look as if it were designed that way.

I'll be certain to get back on (if the customer wants this amp repaired) and let you know of the results...but all seems like it's gotta work.

thanx again, g
