I've started hoarding 112A tubes especially Cunningham as I like that extra mica support. They must have made a ton of these. I'm still going to hoard while I can.
The first two test in the 80's and appear unused. Two of them have the same datasheet.
The third had these extra long sheets wrapped around the tubes packing materials.
Hate it when they have labels. This one test at 70.
I snagged this Silvertone for $2 on ebay and it test high as well.
