ultra-regulation power supply +24V -24V by LM317,LM337

The ultra-regulation of the power supply +48VDC,+24VDC,+16.4VDC is so over the top and unnecessary that most, if not all, people building this amplifier would not even notice the difference. However there are a number of benefits to this design. First its a dual tracking design. Because the open loop gain of the amp is low, its common mode rejection due to the power supply is not great. However if both the + and – voltage rails move up and down the same amount, there is no bias drift.

Dual Power Supply 24V and 12V unregulator

There are two power supplies: one version for the amplifier and muting timer The power transformer secondary supplies about 18Vrms, so the V+ rail is about 24VDC, adequate also for hi-Z headphones. I donâ€™t like regulated power supply units for this kind of circuits, so a simple Pi filter is employed here, made by C2, C6 and R18. The PSRR of the audio circuit is about 30dB. With a 30-Ohm output load, Iâ€™ve measured about 350uV (1uV = 1*10-6 Volts!!); in spite of this, since the Grados are quite sensitive headphones, a little hum can be heard, only if the room noise floor is absolutely low and there is no signal applied at the input, of course.
