According to the "tube Substitution Guidebook" by HA Middleton, 6550 is an excellent sub for a KT-88. If you are worried about any harm/damage, don't worry. Switching these will only change the sound, not the electronics.
Are KT-88 a good substitute for 6550c?
I have a VTL stereo 150 amp that uses 8 6550c tubes. I usually replace them with the Selvtlana 6550c. I was told that the Electro Harmonix KT 88 was a better sounding tube, more romantic less punchier than the 6550's. I would like to try them but don't know if this is a good idea changing tubes.
Does anyone have any expierence with this.
Thanks
