Try an RFI kit from one of those toroid core companies.
It's not unlikely that you will find other household appliances that will
become sensitive once you are on an antenna.
When I got my first commercial amp, an Alpha 87A, I hooked it up to a 160
meter dipole about 30 feet off the ground just outside the shack window.
Watching the SWR carefully I was able to get about 800 watts out. After
calling CW for a few minutes my XYL reported the garage door was repeatedly
opening/closing, the big screen TV in the family room was turning itself on
and off and the remote telephone was un-useable during my transmissions.
Such is life with an amplifier.
Since then I have moved the shack out of the house into an apartment we
built for the in-laws years ago.

Subject: [Amps] My 813GG amp works
Hello all,
Taking some advice about putting that homebrew 813 GG, that I bought, on the
air for a while before I try to modify it for other bands. I to try it on
Saturday night/Sunday morning around 1230 AM for the first time.
The wife was snoozing in bed, I thought... why not give it a go...
So I tuned it up into the dummy load on 3810 kHz, driving it with 65 watts
out of my transmitter through my antenna tuner to match the transmitter and
the amplifier, I flipped the switch the watt meter indicated 650 -700 watts
out of the amplifier and into my antenna, got a "sounds mighty fine" signal
report... and then our house alarm went off... And it wasn't even "armed"
Needless to say, the wife got out of bed... she said, well I guess it works,
but can you not use it again until you figure out how to keep that from
happening again...
I guess the alarm system didn't like that amount of RF, but the amp works!
Now I need to solve that alarm problem...
