new to tubes

Just purchased a tube integrated that is powered by KT88s. The amp allows for swapping those with EL34s or 6550s. Would you be able to describe, in general, what the 'sound characteristic differences in these three tube types are? Thanks

Facten, while a lot of folks will speak out on sonic characteristics, you will find a big variance in sound between the same tubes of different manufacturer ... so much so that you cannot really ascribe a sonic character to any tube. This, coupled with the fact that the design and component quality of an amp has more influence on the amp sound than the tube itself, makes defining the possible characteristic is somewhat academic to say the least.

+++ The 84's are usually transferable with 6550's and KT 88's +++

Not sure how a KT88 or 6550 will fit into an EL84's socket or vice versa. The EL84 is a much smaller tube. They [KT88 & 6550] use identical tube sockets to EL34s, 6L6s etc and these tubes are interchangeable in many amps.

KT88, 6559, EL34 are NOT interchangeable with 300Bs
