What is the difference between original production Genalex KT88 tubes and
original Gold Lions? - The ones made by GEC - Not interested in reissues.

Also, there are different architectures of Genalex KT88's; dual side / dual
top getters,
dual side / single top, dual top... is one considered superior and more
valuable?
Is the Gold Lion version one particular getter arrangement or did they also
come in different styles.

Thanks.
