What separate tube phono stage do you use ?

Yes, Ralph, I got that. Unless I have the tape machine modified. How difficult is it ?

Although NOS tubes are expensive, I would never purchase any that were even more expensive as a result of "exclusivity".

Any NOS tube from military bunch made by Telefunken or Mullard in the 50s or 60s are exclussive nowadays, but you pay more for the brand. Japanese tubes are no so expensive, as far as i know British Mullard made Matsushita tube factory in Japan. Those japanese tubes are really amazing and highly competitive to the best British made Mullard, but for less $ 

Chakster, have you looked into Sugwang tubes?

Inna, you will discover that 15 IPS with a good 2 track is complete overkill; that's for live. 7 1/2 will work very well for records and CD's. Yes CD's; they'll sound more like records on playback.

No, i live in Russia and i don't need Chinese tubes, we still have Soviet Military tubes from the 70's available, some people love them, some Japanese manufacturers (like Luxman) use new Russian tubes in their new made in japan amps. My ex Luxman amp was full of Russian tubes branded Luxman (i'm proud that Japanese manufacturer prefer Russian tubes over Chinese :).

However, NOS vintage Telefunken, Sylvania Gold Brand, Matsushita are on another level compared to all new tubes i have tried, not even close, absolutely different experience, really. However, the Soviet military tubes are cheap as chips and amazing for its price.
