There have been many requests, over the years, for a 20/20 power supply upgrade. Finally there is such. This new Linear Power supply is specific to the 20/20. The one box contains two isolated 48 volt linear power supplies. The truly dual mono nature of the 20/20 is preserved. Simply plug the LPS's DC cables into your 20/20 and enjoy your upgrade.
The LPS is incredibly effective. It is also straight forward in itÂ’s simplicity. Rock solid in performance, stability and reliability. Nothing fussy about it. No active voltage series regulators to add their colorations. No switching regulator noise to deal with. Just a lower noise floor and a more relaxed and effortless presentation.
Power Transformer
The power transformer is toroidal for minimal radiated magnetic field. The already low magnetic field is further reduced by connecting the primary windings in series rather than parallel. The transformer flux density is reduced to half of normal.
The transformer's AC output is full-wave rectified, current-limited and applied to a first stage shunt regulator. That not only gives the first stage of voltage regulation, but it also smooths the current waveform drawn thru the transformer. The usual current spikes become much more sinusoidal in shape. Thus current spikes are not injected back into the power line or project a radiated noise field.
