I agree the RFT is not my fav sound wise. But they hold up. I would tell you that you either go with the cheapest tubes you can and swap them after they go microphonic or go with something really nice. About 15% of the Mullard CV4003 will hang together in that preamp. They have to be perfect going in.....then they seem to make it. From our standpoint as a dealer of gear and tubes it has been a bit frustrating.
