I've been really enjoying the blue glass JJ KT88 power tubes in my Jolida JD-502P amplifier. I've paired them with a pair of Mullard CV4024 type 12AT7 tubes and JJ 5751s. Very clean tone and wonderful bass.
I hope others can give this power tube a try in their amps. They aren't the most expensive tube out there so I'm guessing they may get overlooked by the audio community.
One thing I'm wondering about with these tubes when they are biased. With my Jolida amp as soon as I turn it on the bias lights on the Jolida turn on within minutes. With other KT88/6550 tubes and even the Tung Sol KT-120 power tube the Jolida would reach proper bias in about 20 minutes to 1/2 hour. Has anyone experienced this as well with their amps and JJ KT88 tubes?
