Lew,
Coupla things. I measured the frequency response not only with a Radio Shack meter, but with an HP audio analyzer with averaged readings. Approximately the same result.
At the same location, simply replacing the Atma's with an Edge ss amp made a very big difference. Now the response was normal.
That you are driving the SL's with measured impedance less than 2 Ohms at high frequencies gives me hope that my tubes are at fault. I should find that out sometime tomorrow.
Looks like I was facing a couple of problems--bad initial hookup, bad tubes--which have kept throwing me off. Two problems together are more than twice as hard to solve as one problem.
I'm hoping that replacement tubes will signal the end of my difficulties and that I can indeed enjoy my system again.
I sent you an email. If you don't get it, check your SPAM file.
Regards,
Chuck
