I've had the original RM-9 for ten years. No problems whatsoever. I concur with the above posts but think that the KT-88 is way better sounding than the EL-34 or 6550. Buy one, you'll probably own it for life.
The two front driver tubes will have a audible effect on sound quality. I've settled on NOS Amperex orange globe (Holland) a-frame 6dj8. Very smooth but still detailed.
