Well, I have one week holiday and I’m almost dead because of doing nothing. Since I have a pair of Aikido 9-pin Preamp PCB, why don’t I build one?

The main concern of this project is simplicity and cheap price. I don’t want to spend too much money for this project (just to kill my boring days).

So here is the PCB. Nice, sweet, well build by John Broskie.

Well, I need a big-capacitance high-quality capacitor to drive my headphone amplifier (we are talking 200-500uF capacitance and at least 400VDC working voltage). I don’t have too many choices (or perhaps no choice at all!). So I would go with this Unlytic Film Capacitor.

Yes I could go with Electrolytic capacitor but the sound would be not at my expected level.

So I welcome “The Giant” Unlytic capacitor Want to know how big is it? Keep reading.
