My Dynaco Pas 3 Series II has Sovtek tubes which gives the pre-amp a very sterile, almost solid state sound. In fact, in A/B tests with the same speakers it was difficult if not impossible to distinguish the Dyna from NAD solid state.
I have been told that NOS Telefunken's were the only way to go, but not wishing to spend $500 on tubes, I am looking for a better choice. It is my understanding that Tung-Sol's 12AX7 tubes were very popular and sound great, plus are current production and cost around $16 each.
Any feedback from you "Tube Junkies"?
