KT 88 with Leben cs 600

@mdrone Plate voltage on the Kt88 is dealers choice. With the switch in the “up” position the KT88’s will be slightly more resolute. With the switch in the “down” position, the KT88’s will be slightly softer. You may or may not notice much difference. I believe the CS600x sounds better with EL34’s or 5881’s or KT66’s. One man’s opinion.

The 600x ships with el34’s or 5881’s. I prefer these two varietals. Ive listened to kt77’s and some prefer them…
