[tonycamp]

Anyone have info on what the portugal marking defines(beside the obvious made in)? I believe the 5532/4 are Texas instruments? I'm just researching where these were built and what ever else? they are in my Soundcraft Delta8 Master.

thanx for any info

There are a few different of different brands of 5534/32.  Signetix, Philips, ST spring to mind.  From memory the Philips version might have been made in Portugal.
