Good quality KT88 power tubes?

try penta labs they have a new kt88 from china thats very good much better than the sovtek you can call them at 800 421 4219 ask for jamal

Albert, your right about checking with the manufactuers on what tubes can be used with there amps. my amp can use the the kt88 6550 kt90 kt100 [Rogue 88 ] they use the sovtek kt88 because it a good tube thats reliable, but they do like the sound of the tubes from Penta labs kt 88, they sound WAY better than the sovtek, Also Svetlanta has a new kt 88 comming out too! greg
