- Notes
- Balkeit, Balkite, Pfanstiehl are put together to Fansteel. One dial (primary tuning control knob).
The Symphion models employ a UX210 tube as an oscillator at about 3000 kHz, to supply the filaments of the five 201As ! Thus avoiding hum and permitting use of the 201A (which is considered superior) in an electric set.
