I'd stick a 100-200 pF cap before the ferrite directly to the chassis.
I did a lot of work in an EMC chamber about 20 years ago. Without the devices I would not have gotten the products through Qualcom and eventually accreditation. Testing was IIRC 50MHz up to 3GHz. Very tough to pass, but we made it.

Found a copy of Walt Wood's dowsing kit while doing the laundry (no idea where it came from). It's pretty easy to get the hang of the standard J-hook dowsing rods, they want to act like they have a mind of their own. I kid you not, in less than a minute I could walk past the cold water line and the thing just kept pointing right at it. I'm impressed. The map dowsing with a pendulum is impressive too as well as using dowsing to neutralize GMO foods.

I keep 1 nF ceramic capacitors in the kit with the beads. Just very hard to get the local 50 KW 1020 kHz AM station out of nearby systems. Then are the folks with light dimmers so much noise so close to audio.. Very fond of input transformers.
Scott,
I don't know if you are kidding or ill! 🙂
Yes, I found the Madison ad as well. Looking it over, I notice that it seems all three dirvers used in by speaker boxes are still on offer, although their markings seem t have changed as well, so my tweeter is now gold plated (WTF?), but the price is still about the same, $ 110 per piece, in 2002 mine cost €97 (catalog list price, I actually paid less, the company owner is a friend of old). I'm not surprised, in their time they were considered the best from Audax.
I also saw quite a few models which were used by JBL in their commercial modles while they were being made in Denmark. The pro drivers were never generally sold, although JBL would sell them on specific request, but don't ask about the price, not good for your health.
You should read up on the dowsing culture, if I train hard enough I should be able to pick out the best resistors. No I actually found this is a pile of stuff we are culling from the mess, in getting ready to possibly move. Seems OP and rather dear for what it is. I'm sure my wife paid a $1 or two for it.

I will believe that if you train hard enough that you can pick out the best resistors, but not by dowsing, physics and engineering would get you there faster. OP??
Hovland went under inspite of their tube and transformer dowsing. And the dowsing dude claimed to have a brother that could dowse for gold. With all that, no Hovland and no gold. It may find water, but I ask; Then wouldn't all the dowsers be here in California making a killing and I could take showers without guilt?
My guys picked up a case of bottled water at the local Home Depot. It was labeled as produced in California! Then you do know where much of the Budweiser beer is produced? L.A.
I am pretty sure I have mentioned my great uncle was issued a horse and two mules to help with making the maps to do the dam at Boulder and irrigate your neck of the woods.
They may all have been so obsessed with striking water, that they carelessly threw away the nuggets in the process, and died of thirst.
And huge amounts of Cali' water is used to grow Almonds that are shipped to China!

But "thank you" to your great uncle.
Sorry, that should have read qualification and not Qualcom.
F;;(;🙂g Apple spell corrector again.
One of my work colleagues about 35 years ago was designing an SMPS. Anyway, for some reason he put a ferrite bead on the lead of the secondary smoothing cap. The ferrite bead was HOT - you could not touch it.
Well, he claims they found the big chief!
Do you think you could find the Perrier?

Van Nuys, specifically. Most around here is from Houston. PA probably gets mostly Columbus and Newark Bud.
