Can I swap 6L6 for KT88?
You really ought to increase the power of your output transformer if you’re going to move from 6L6 to KT88. a pair of 6L6 generally puts out about 35-45w. a pair of KT88 is about double that. that’s great if you want to increase the wattage of your amp, but be sure your output transformer can handle it.

There is a misnomer that the KT88 can handle 800 V on the plates, the original spec and this is for the original tube design is: 600 V on the plate and 600 V on the G2. This is one reason the tubes were blowing up in the Marshall Major amplifier, which averaged 620 V on the plates.
What do you think about the JJ KT88?
The JJ KT88 is an amazing tube! They are extremely thick and rich sounding with no loss of high end like the chinese made KT88’s. Most amps using 6550’s can also use the JJ KT88’s for a different sound. You want THUNDER from your vintage Ampeg SVT?
