the JJ KT66s look exactly like their KT88 - wouldn't be surprised if they were the same tube that was labelled according to what orders they have in (or VERY minor constructional changes).
can't go wrong with Shugang KT66s at the price they go for, great sounding tubes that I've had no problems with.
