I use Telefunken CCa's in mine and love them in the phono. I have also used NOS Telefunken 6922's also a super tube go and try you may like it . I like the sound with a Siemens 6922 or CCa's in the line stage but you could also try a 6922 Phillips Holland SQ miniwatt NOS or a Amperex PQ 6922 Holland NOS . This is what I use and love the sound just My two cents
"Telefunken ECC88 RFT made, 1960's in AI M3A?
I would like to use these in my Audible Illusions M3A pre-amp. Has anyone else used them in theres?
