There are so many! Any older CJ preamp. A wonderful tube preamp is the LInear Tube Micro Zotl with power supply. This is the venerable David Berning design! I love that one with Tungsol round plates. Backert Labs makes a great preamp, Modwright, Supertek is wonderful plus you can get a phono stage for that price, Don Sachs is also highly regarded, Atmasphere, Cary etc. I also liked the Doge 8 with NOS tubes (about $1400 new.) All are great and I probably forgot about 10 others.
It is a great time to be an audiophile with all the great choices new and used!
