Ait - I am using RCA NOS 6SN7. I am sure there are other good ones as well.
As to those who ask "WHY?" or "How much?", why not a Supratek over any other for your first? The cost can be determined by going to Mick's website.I am sure he has read the thread and read comments of other happy owners. The cost/quality ratio of the Supratek line is pretty hard to beat IMHO. It has one of the finest phono stages of any pre, regardless of price.
