What does the Kel84 sound like??

[Primalsea]

The only amps I have herd recently using EL84 valves was a small Yarland Amp that a friend bought from Ornec and a Leak Stereo 20.

Has anyone herd either of these amps and a Kel84? If so would you be kind enough to advise using the other amp as a basis for comparison. If not, just some kind of indication anyway.

I'm thinking about buying a kit and just want a general idea of what it sounds like.
