I would recommend the (blue label) GEC KT88 for this pre. I experimented with Gold Lions and Gold Monarchs as well. These are 3 variations of the vintage Genalex KT88, not re-issues. While the I preferred the GEC best, it leaned towards the euphonic side. Despite its imperfections, it made going back an impossibility. I decided to either use this pre with the GEC or not at all. I still have the GEC if anyone wants to try it.
