Hi, I have a set of Ayon Audio mono's that use KT88 tubes. Over time I've purchased their importers version of the KT88's that are 200 bucks a pop. Can I use a different tube? I think I'm paying premium cash for the Ayon name on the tube.
If it takes KT150s get the Tungsols from Upscale. I have used KT88, KT120, KT77, 6550, and EL34s in my PL Dialogue Premium and the 150s are great. Balanced and the midrange is sweet, no zingy top end and no bloated bass.
