dbx rms 208 module for 160VU

[Rob Flinn]

I have a rms module that needs repairing.  Going on what Joe says in the post further up this thread.  I am going try replacing the op amps tomorrow.    Can I sub something else in that I have here apart from an LM301 ?  5534 or TL071 ??

I sorted this out it was one of the op amps.  I swapped both out for 5534's so they were the same & it seems to be working fine.

I am trying to shotgun a couple of these bad RMS cards, but I cannot track down any CA3083 chips anywhere and I dont trust the ebay ones. Equivalents dont seem to be very obvious either, does anyone have any recommendations to source these?

Had good luck with freelance electronics in the past but can't decipher what they have in stock....

also had success with rose electronics for some chips... too lazy to decipher stock...

Interestingly enough, I unpotted one of them and it looks nothing like my other ones, or the examples provided here. Anyone have insight into what this is? I am guessing it was a different model someone repurposed?
