Hammarlund and Homebrew Heroine: Janis AB2RA, HQ-100 Filter Cap Question

I was searching for Hammarlund HQ-100 wisdom when Google pointed me to the
Electric Radio articles of Janis AB2RA. They were in ER #380 and #381
(February and March 2021). Lots of good stuff in there.
This morning I happened upon a 2014 SolderSmoke blog post (as you do) about
my Tuna Tin 2. Turns out that Janis was my first contact with this rig.
And she too was running a homebrew rig. TRGHS.

I continue to work on my HQ-100. The AC hum is getting worse so I have
ordered a replacement capacitor can from Hayseed Hamfest. But I was a bit
confused about which cap to order. Hayseed has two caps listed for the
HQ-100 -- one (it seems) for the early model of this receiver and one for
later models. Is that right? Did Hammarlund update the power supply to
add filter capacitors? Take a look:

Dean KK4DAS is getting ready to work on his dad's HQ-170A. He too will
find lots of wisdom and tribal knowledge on Janis's wonderful web site.
Her main page: http://www.wireless-girl.com/ (with a vast amount of
technical info available through the links on the upper left side of this
page)

Thanks Janis! The Original Wireless

Forbes has an interesting article that may help explain the poor Cycle 25
propagation that were talking about in SolderSmoke podcast #238:
