Hi all,
I have been a fly on the wall here for a while but am about to embark on my first (of many) MIDIbox projects.
In the run up to a mb-6582 using 8 x 6582A, I am thinking about building a stereo 6581.
I have a chip already and am looking at buying another which is the same revision, manufacturer and year but was made 5 weeks earlier.
Is this close enough for a good stereo match, or do they deviate even from week to week?
The chip I have is an MOS R4AR.
Cheers!
