Larry: What's your preference for Dolby, or none at all? I wouldn't worry much about any surface noise from recordings made from vinyl that make it to cassette. I don't use any form of noise elimination, digital or analog. My dbx 3BX does help a bit in that regard and I have used it sparingly when needed. If I like the song on vinyl enough to include it my track set, I do the best I can cleaning the record. My vinyl is in good to very good condition, but during those quieter passages, invariably there's a bit of noise.
Last night, I recorded a copy of "Deserted Island Mix 2014" for Ian (ianC90 of TH) and it's on its way to him. So, your copy is next. I can record it on a Phoenix Blue, if you like, but I will be keeping the peak recording levels below +3dB.
Nando.
