Vintage pre-1970 GE, RCA, Sylvania, Mullard and Telefunken are still the best made and sounding of the 12a*7 types! Far better (and longer lasting) than present day production! That is why they command high prices!
Question for tube aficionados
I have a vintage Conrad-Johnson PV 11 preamp.
I’ve always re-tubed it with the cheapest tubes from Tube Depot (e.g. Electro-Harmonix 12AU7 and 12AX7, Sovtek 5751 and the like.). I’ve been very happy with the sound.
My question is:
Would it be worthwhile to spend more money on more exotic tubes?
Would there be any appreciable difference in the sound?
I’m powering the system with NuForce Reference 9 V3 monoblocks.
