Pre-Amp Power Supply Upgrade ????

Bill if a former Conrad Johnson engineer and knows preamps. He also
does power supply upgrades. He upgraded the power supply on my
CJ/Motif preamp with good results.

I'm with Scott on this one. There are some old amps that would produce 200+ wpc @ 8 ohms with less than 10,000 uF's of capacitance in them. As such, 50,000 uF's is more than enough for any preamp.

Keep in mind that if you turn this preamp off and on as you use it, those caps have to "fill" or "charge". This is a LOT of "in-rush current" for the power supply components to deal with, so adding more could actually increase the wear and tear on the equipment. If you leave this unit turned on all of the time, it is not a big deal other than for the initial turn on and the occasional power down / up when doing maintenance. Sean

The YBA 1 preamp have 100 000µF of decoupling

Other than a higher price and a more crowded layout, what does that exhorbitant amount of capacitance buy you in a preamp though ? Sean
