I have a NOS unused Mullard for the Sonic Frontiers SFl-1 Siganture I used to have I got from the Parts Connection. I'd part with it for $ 35. I also have a Telefunken I got from Kevin deal with about 60 hours on it for $145. They are quite rare.
Tube recommendation for SFL1
Thanks for those who recommended SFL1 for my Bryston 3BST amp with B&W CDM1SE and two Kimber 8TC biwired. Since I am new to Tube amp, could you also recommend good tubes for SFL1? How much do I expect spend on tubes and what are their lives in general? Thanks much. Danny.
