Hello everyone!

I have a question. Is it possible to replace the KT88 in the Pittbull UL with a KT120?

Best regards, Sascha

Hey Sacha, welcome to the forum.

There is no reason you can’t use KT120s in the UL. Just remember that 120 refers to how much power the tube can supposedly dissipate. Not how much power your amp will produce. That last bit is determined by the power supply.

So don’t be surprised if the amp gets stiffer and less playable.

Hey Dave.

Thanks for the reply.
I think I’ll just give it a try.
