I think I forgot to mention...I have **no** audio issues with the L7, only
the Henry. Go figger!
OH, and I have very little (read: next to none!) RF in the shack. That is
what is puzzling me! How in the heck is the RF getting into my network and
only affecting the printer?

Hi again,
Given the old amp caused issues with your audio, and your new amp causes
issues with your network, we can assume you have some level of Common Mode,
(CM).
My first step would be to buy or build a common mode sniffer. MFJ makes one
for around $100.00, or you can build one for around 10 bucks:

nts-or-rf-in-the-shack
If after testing with that you discover lots of CM, then start choking it on
the booth ends of the feed-line.
That may solve both your RFI issues; audio, and Networking.
If that does not solve things report back here with results. The AC would
be the next thing I would look at...
73s and thanks,
Dave
