[drakelist] 2nd IF Audio Board in TR7

[David & Chris Drake]

Hi all, 
Couple questions:  Is there a significant performance difference between the 
first and second version 2nd IF/Audio boards?.  I believe Drake changed to the 
newer version along the time the R7 came out, but not sure exactly.  And: If 
the answer to the first question is affirmative, then is there anyone out there 
who has performed the upgrade on and early board?  Good results?
Thanks,
David
