My “regulated monster” is currently running 0.5-0.6 Amps bias per Hiraga’s recommendations in the article. I tested the power supply which you may recognize as the PCB for the John Linsley-Hood simple Class A amplifier 1996 version from Williams Hart Electronics. I have upgraded the supply with LM338K TO-3 case regulators in lieu of the original LM338T TO-220 regulators (see LM338 Voltage Regulator Calculator for more information). On the bench the supply measures very well in this configuration with below 160-200uV of ripple pk-pk under a 2A series load. Despite this low level of noise, I would like to try the battery supply for its huge current capability and as close to zero noise as possible.
