The one and only Svetlana 6550 winged C.If you can find one that works better,please let me know.
I bought mine at tubemogul on ebay and they are all from early 2000 and worked fine for me.
Good stuff,thanks,Ive got one.I currently prefer a nos GE 6550a.
I cant go back to the sovtec,so well see what else is happening,cheers.Tung sol black plate mite be worth a try
I use the Tungsol 6550 Blackplate , same as in the CD REF 7.
Up until now there is none better .Fortunately I have bought spare blackplates for both units
