| The ideal power supply for all Thorens record players running on 15 - 18 Volt A/C (not the 800 Series). |
The transformation of a mains voltage supply (110…230V A/C) down to a smaller voltage (15…18V A/C) always generates phase shifts which in turn are the cause of increased vibration and wow and flutter in any low-voltage motors that are synchronised by the mains A/C. And, if a power transformer has to operate under a strong load, those phase shifts are even augmented. Although a well-dimensioned power transformer (e.g. torroidal transformers) can minimize phase shifts, they can not be totally eliminated. This is why the TPN 2000 comes with a massive power transformer (switchable to 100V, 115V, 230V and 240V) plus an isolation transformer, which is able to eliminate nearly all phase shifts. In addition, this combination makes an extremely effective mains filter! Many listening tests have confirmed the effectiveness of isolation transformers as part of an audio chain as the results are, generally, clearly audible. | The TPN 2000 also features a phase switch on its rear panel, which can be used to determine the optimal electrical phase of the mains supply within your hi-fi system. |
