Title: EAA PSP-2 Bench Tests
Post by: hi and lo on January 27, 2012, 02:40:01 PM

This is what Vark sent back to me when they fixed a broken switch on my PSP-2. Thought they might be interesting to a few folks around here:

Those are interesting.  Thanks!

Now, what tortured conclusions can we force out them.... ;)

It looks pretty flat, with just a bit of channel imbalance.  It would have been interesting if they'd taken a post-repair test without the roll-off filter engaged.
