I've been informed that my 60 watter will support the KTs without any tranny upgrade or other mod. The combos, unlike the heads, have adequate spacing for the big bottles. The right pair would evidently bias right with this amp, which is still fixed. haha- would be a 100 watt 5150.
Anybody have experience with the KT88s in a 5150/6505/6260/ect?
The KT vs. 6L6gc, sound wise?
I've heard of people putting 6550s in 6505s before to great effect, which IIRC are supposed to be similar to KT-88s. Go for it.
