Yes, I did, I tried the KT88 from my Pittbull Ultralead once.
Bigger allover, smoother mids and the typical KT88 satin-like hi's.
On the other side, I experienced a tad bit -hardly noticeable- reduction in power amp overdrive which didn't bother me too much though since the smoother mids make up for it in a way.
However, I reverted to the stock EL34 as I feel it's more authentic with the Thin Lizzy cover band that I use to play this amp in.
If I'd be more into Blackmore or modernish sounds with this particular amp I'd definitely give the KT88 another try.
I should add that I'm playing an 1960AHW cab.
Can't really imagine how well the KT88 would go with the T-75 or V30.
