The sonics, you are describing, will not be found, with Telefunkens, and especially Mullards. These are rich, warm, lush sounding tubes. With the richness, and warmth, fast transients, are not part of the package. Both have a soft bass, the Mullards, are mushy. The tube closest to the sonics you are asking for, is the Siemen Halske. The Siemen Rohre, are very close, but lack the hint of warmth, you ask for. Transparent, airy, detailed, with a tight bass. If you use the Siemen Rohre, you could try to use, say a Telefunken 12AT7, to restore the warmth, that the Siemen Rohre, lacks.
