I have several GE 5AR4's. Three are Made in Great Britain and are
Mullards. One is Made in USA and has the distinctive copper strip
visible on the side of the plate. I know about this from the Angela
catalog. And two are Made in Great Britain, but are not Mullards. In
particular, these have fewer notches in the sides of the plates and no
visible copper-colored laminate (as is slightly visible on a Mullard).


I know the Mullards are killer tubes that work great and last
forever. I was wondering about the others.


Thanks for info, tube gurus.


-Henry

I have three made in great Britain, one a Scott (maker unknown), one with logo rubbed off, and one RCA. They appear identical to
each other. The plates each have two vertical perpendicular ridges. The top view would look like two crosses. There is no copper
laminate.
